10" Hybrid Hand Cup For Flat Or Curved Surfaces

Wood's Powr-Grip N6300 — 10" Hybrid Metal Handle Flexible-Edge Vacuum Hand Cup for Flat and Curved Surfaces (175 lbs / 79 kg)

The Wood's Powr-Grip N6300 is a heavy-duty vacuum hand cup engineered for fast, reliable attachment to both flat and curved smooth, nonporous surfaces with a rated load capacity of 175 lbs (79 kg) — the highest single-cup capacity in the standard Wood's Powr-Grip hand cup lineup. Featuring a 10" (25 cm) standard rubber suction pad (Model G0750) with a flexible vacuum pad edge, a metal handle, and an economically replaceable industrial-grade plastic plunger, the N6300 delivers the highest-capacity flat-and-curved performance in the WPG lineup in a hybrid construction that balances handle durability with plunger serviceability. The flexible pad edge enables fast, reliable attachment on both flat surfaces and curved surfaces with a minimum radius of 13" (330 mm), making the N6300 the most versatile high-capacity cup in the standard WPG range. The N6300 (SKU: 91640, Model: N6300) is manufactured by Wood's Powr-Grip and ships with a protective carrying case.

The N6300 is the 10" hybrid counterpart to the 9" N5300 (hybrid, flat only, 150 lb) and the all-metal N6450 (metal handle and plunger, flat+curved, 175 lb, 13" radius). Where the N6450 uses an all-metal handle and plunger for maximum durability, the N6300 uses a hybrid construction — metal handle for grip rigidity, plastic plunger for economical replacement — at the same 175 lb capacity and 13" minimum radius. The N6300 also adds the flexible pad edge that the N6450 does not have, enabling faster attachment on curved surfaces by conforming to the surface profile rather than requiring the flat pad to flex against the curve. The G0750 pad is shared across the N6000, N6300, and N6450, making replacement pads interchangeable across all three models.

Key Features & Benefits

Flexible Vacuum Pad Edge — Fast Attachment on Both Flat and Curved Surfaces

The N6300’s flexible vacuum pad edge conforms to the surface profile of curved materials, enabling fast vacuum seal formation on curved surfaces without the extended pumping effort required when a standard flat pad must flex against a curve. On flat surfaces, the flexible edge seats fully and provides the same large-area seal as a standard flat pad. This dual-surface capability — flat and curved from a single cup — makes the N6300 the most versatile high-capacity cup in the standard WPG lineup. The flexible edge also accommodates flat materials that may bend or flex slightly when lifted, similar to the N5300’s application on deflecting flat panels.

Hybrid Construction — Metal Handle with Economically Replaceable Plastic Plunger

The N6300’s hybrid construction combines a metal handle — providing the grip rigidity and structural durability needed for controlled lifting of heavy panels up to 175 lbs — with an industrial-grade plastic plunger that is economical to replace when worn. This design balances the durability advantage of a metal handle with the cost-of-ownership advantage of a replaceable plastic plunger, making the N6300 a practical choice for high-use professional environments where plunger wear is a routine maintenance consideration. The plastic plunger is available as a replacement component through Wood's Powr-Grip authorized distributors.

175 lb (79 kg) Rated Load Capacity — Highest in the Standard WPG Hand Cup Lineup

At 175 lbs (79 kg), the N6300 shares the highest load rating in the standard WPG hand cup range with the N6000 and N6450, enabling single-operator handling of large, heavy curved and flat panels that would otherwise require mechanical assist or multi-person lifts. This capacity covers the majority of large architectural glass panels, heavy stone slabs, and large curved building envelope panels encountered in professional glazing, stone fabrication, and architectural installation work.

Flat and Curved Surface Compatibility (Min. 13" Radius)

The N6300 is rated for both flat and curved smooth, nonporous surfaces with a minimum curved surface radius of 13" (330 mm), matching the N6450 exactly. Unlike the N6000 (curved surfaces only), the N6300 handles both flat and curved applications from a single cup — making it the correct choice for operations that handle a mix of flat and curved panels and want a single high-capacity tool for both. The 13" minimum radius covers the majority of curved architectural glass, cylindrical glass, and curved stone panels encountered in professional installation work.

10" Standard Rubber Suction Pad (Model G0750)

The 10" (25 cm) G0750 pad provides the largest contact area in the standard WPG hand cup lineup, improving vacuum retention and seal stability on both flat and curved surfaces. The G0750 pad is shared with the N6000 and N6450, making replacement pads interchangeable across all three models — simplifying pad inventory management for operations that stock multiple high-capacity WPG cups. Replacement pads are available separately through Wood's Powr-Grip authorized distributors.

Red-Line Vacuum Loss Indicator — Protective Carrying Case Included

The built-in red-line indicator provides a continuous visual warning if vacuum pressure drops significantly during a lift. The N6300 ships with a protective carrying case that keeps the flexible-edge pad clean and protected — proper pad storage is especially important for the flexible edge, which must remain free of deformation and contamination to seal correctly on curved surfaces.

Common Applications

Large Curved Architectural Glass Installation

Glaziers handling large curved architectural glass panels — including curved curtain wall panels, barrel vault glass, and large-radius curved storefront glass — use the N6300 for its combination of 175 lb capacity, flexible-edge curved surface attachment, and hybrid construction. The flexible edge provides faster attachment on curved surfaces than the standard flat pad of the N6450, while the metal handle provides the grip rigidity needed for controlled positioning of heavy curved glass.

Heavy Flat Glass Panel Handling

On flat surfaces, the N6300 functions as a high-capacity flat-surface cup equivalent to the N6450, handling heavy plate glass, tempered glass, and architectural glass panels up to 175 lbs. The flexible edge also accommodates large thin flat panels that may deflect slightly under their own weight when lifted, maintaining the seal through minor panel flex.

Mixed Flat and Curved Panel Operations

For glazing contractors and stone fabricators who handle both flat and curved panels in the same operation — such as curtain wall projects with both flat and curved glass units — the N6300’s flat-and-curved capability eliminates the need to carry separate cups for each surface type. A single N6300 handles both, reducing tool inventory and simplifying on-site logistics.

Heavy Curved Stone and Countertop Handling

Stone fabricators working with curved granite, marble, and engineered stone profiles use the N6300 to safely lift and position heavy curved stone sections. The 175 lb capacity accommodates most curved stone sections, and the flexible edge enables faster attachment on curved stone profiles than a standard flat pad.

Large Curved Architectural Panel Installation

Installers working with large curved composite panels, curved ACM, and other curved architectural building envelope elements use the N6300 for its combination of high capacity, flexible-edge curved surface attachment, and hybrid construction suited for professional installation environments.

High-Use Environments Requiring Economical Plunger Replacement

Operations that use 10" high-capacity cups intensively benefit from the N6300’s economically replaceable plastic plunger, which reduces the cost of routine maintenance compared to all-metal plunger models like the N6450. The metal handle provides the durability needed for high-cycle use while the replaceable plunger keeps maintenance costs manageable.

Application Instructions

Step 1: Surface and Material Assessment

1. Confirm the surface is smooth and nonporous — do not proceed on rough, textured, or porous surfaces.
2. For curved surfaces, confirm the radius is 13" (330 mm) or greater.
3. Verify the panel weight does not exceed 175 lbs (79 kg).
4. Clean the pad contact area — remove dust, oil, moisture, and debris.

Step 2: Pad Inspection and Preparation

1. Inspect the G0750 pad and flexible edge for cuts, tears, deformation, hardening, or contamination. Replace if damaged — a damaged flexible edge will not seat correctly on curved surfaces or deflecting flat panels.
2. Wipe the pad face clean before each lift.
3. Ensure the pad is at operating temperature (above 10°F / -12°C) before use.

Step 3: Attaching the Cup

1. Position the pad against the surface — on curved surfaces, the flexible edge will conform to the surface profile; ensure full perimeter contact around the pad edge.
2. Engage the vacuum mechanism using the metal handle/plunger until firm resistance is felt. The flexible edge enables faster vacuum formation on curved surfaces than a standard flat pad.
3. Check the red-line vacuum indicator — confirm it shows a stable, full vacuum before lifting.
4. Apply a controlled test load (firm downward pull) to verify seal integrity before committing to the full lift.

Step 4: Lifting, Positioning, and Release

1. Lift smoothly — avoid sudden jerking motions that can break the vacuum seal.
2. Monitor the red-line indicator continuously throughout the lift and during positioning.
3. Do not exceed the 175 lb (79 kg) rated load capacity.
4. Lower the load fully to a stable surface before releasing the vacuum.
5. Engage the release mechanism slowly and in a controlled manner.
6. Clean the pad after use and store in the supplied protective carrying case — protect the flexible pad edge from deformation during storage.

Frequently Asked Questions

Q: What is the difference between the N6300 and the N6450?
A: Both are 10" flat-and-curved cups with 175 lb capacity and 13" minimum radius. The N6300 has a hybrid construction (metal handle + replaceable plastic plunger) and a flexible vacuum pad edge that enables faster attachment on curved surfaces. The N6450 has an all-metal handle and plunger (maximum durability) and a standard flat pad. Choose the N6300 for the flexible edge advantage on curved surfaces and economical plunger replacement; choose the N6450 for maximum all-metal handle and plunger durability. Both use the G0750 pad — replacement pads are interchangeable.

Q: What is the difference between the N6300 and the N6000?
A: Both use the 10" G0750 pad and 175 lb capacity. The N6300 handles both flat and curved surfaces (min. 13" radius) and is sold individually; the N6000 is rated for curved and irregular surfaces only and is sold as a Pack of 4. The N6300 also has a flexible pad edge and a metal handle (vs. all-plastic on the N6000). Choose the N6300 for flat+curved versatility and metal handle durability; choose the N6000 when multiple cups are needed for coordinated lifts and lightweight plastic construction is preferred.

Q: What is the difference between the N6300 and the N5300?
A: Both are hybrid cups (metal handle + replaceable plastic plunger) with flexible pad edges. The N6300 has a larger 10" pad, higher 175 lb capacity, and is rated for curved surfaces (min. 13" radius) in addition to flat. The N5300 has a 9" pad, 150 lb capacity, and is rated for flat surfaces only. Choose the N6300 for higher capacity, larger pad, and curved surface capability; choose the N5300 for flat-only applications where the 9" pad and 150 lb capacity are sufficient.

Q: Why is the plunger plastic if the handle is metal?
A: The hybrid construction is intentional — the metal handle provides the grip rigidity and structural durability needed for controlled lifting of panels up to 175 lbs, while the industrial-grade plastic plunger is designed to be economically replaced when worn. The plunger is a wear component that experiences repeated engagement and release cycles; making it replaceable in plastic keeps maintenance costs lower than an all-metal plunger design.

Q: Is the G0750 pad interchangeable with the N6000 and N6450?
A: Yes. The N6300, N6000, and N6450 all use the G0750 standard rubber pad (10" diameter), making replacement pads interchangeable across all three models. Note that the N6300’s pad includes the flexible edge feature — confirm with your WPG distributor that the replacement pad includes the flexible edge when ordering for the N6300.

Q: What replacement pad does the N6300 use?
A: The N6300 uses the G0750 standard rubber pad (10" diameter) with flexible edge. Replacement pads and plunger components are available separately through Wood's Powr-Grip authorized distributors.

Q: Is this product made to order?
