8" Industrial-Grade Plastic Hand Cup with Low-Marking Vacuum Pad for Flat Surfaces

Wood's Powr-Grip N4000LLM — 8" Industrial-Grade Plastic Handle Vacuum Hand Cup with Low-Marking Pad for Flat Surfaces (125 lbs / 57 kg)

The Wood's Powr-Grip N4000LLM is specifically designed to lift flat smooth, nonporous surfaces without leaving marks or stains. Featuring an 8" (20 cm) low-marking rubber suction pad (Model VPFS8L) with a specially formulated rubber compound that avoids leaving marks or stains on sensitive surfaces, an industrial-grade plastic handle and plunger, and a rated load capacity of 125 lbs (57 kg) on flat surfaces. The N4000LLM is the correct choice when the surface being lifted cannot tolerate the residue, staining, or marking that standard rubber suction pads may leave — including coated glass, polished stone, painted panels, and finished architectural surfaces. Protective carrying case included. The N4000LLM (SKU: 91405, Model: N4000LLM) is manufactured by Wood's Powr-Grip.

The N4000LLM is the low-marking counterpart to the standard N4000. Both use an 8" pad and 125 lb capacity on flat smooth nonporous surfaces. The critical difference is the pad: the N4000LLM uses the VPFS8L low-marking rubber pad instead of the G0695 standard rubber pad. The low-marking pad is not interchangeable with the G0695 — replacement pads must be specified as VPFS8L. The all-plastic handle and plunger construction (vs. all-metal on the N4000) is a secondary differentiator that reduces the risk of surface scratching from accidental handle contact on sensitive finished surfaces.

Key Features & Benefits

Low-Marking Rubber Pad (Model VPFS8L) — Specially Formulated to Avoid Marks and Stains

The N4000LLM’s defining feature is its VPFS8L low-marking rubber pad, which uses a specially formulated rubber compound designed to avoid leaving marks, stains, or residue on the surface being lifted. Standard rubber suction pads can leave circular marks, rubber residue, or staining on sensitive surfaces — particularly on coated glass, polished stone, painted panels, and finished architectural surfaces. The VPFS8L low-marking compound minimizes this risk, making the N4000LLM the correct choice for any application where surface appearance after lifting is a quality requirement. The VPFS8L is a distinct pad model from the G0695 (standard N4000) — replacement pads must be specified as VPFS8L.

All Industrial-Grade Plastic Handle and Plunger — Reduced Surface Scratch Risk

Both the handle and plunger are constructed from industrial-grade plastic rather than metal. This reduces the risk of surface scratching from accidental handle or plunger contact on sensitive finished surfaces during the lift and positioning process — a secondary safety feature for applications where surface finish protection is critical. Industrial-grade plastic provides sufficient structural rigidity for the 125 lb rated load while eliminating the metal-on-surface contact risk of all-metal cups.

125 lb (57 kg) Rated Load Capacity — Flat Smooth Nonporous Surfaces

Rated for loads up to 125 lbs (57 kg) on flat, smooth, nonporous surfaces — identical to the standard N4000. The low-marking pad does not reduce load capacity relative to the standard rubber pad.

Red-Line Vacuum Indicator — Protective Carrying Case Included

The red-line indicator warns of any significant vacuum loss during the lift. The N4000LLM ships with a protective carrying case to keep the low-marking pad clean and protected between uses — pad cleanliness is especially important for low-marking applications, as contamination of the pad face can transfer to the sensitive surface being lifted.

Common Applications

Coated and Treated Glass Handling

Glaziers and glass processors handling coated glass — including low-e coated glass, reflective coated glass, and decorative coated glass — use the N4000LLM where standard rubber pad residue or marking on the coating surface is unacceptable. The low-marking pad minimizes residue transfer to the coated surface.

Polished Stone and Finished Architectural Surfaces

Stone installers and architectural contractors handling polished granite, marble, and engineered stone with high-gloss finishes use the N4000LLM where standard rubber marking on the polished face would require additional cleaning or could damage the finish.

Painted and Finished Metal Panels

Fabricators and installers handling painted, powder-coated, or finished metal panels use the N4000LLM where standard rubber pad contact could leave marks or residue on the finished surface.

Quality-Critical Flat Surface Handling

Any flat smooth nonporous surface application where surface appearance after lifting is a quality requirement — including display glass, architectural feature panels, and finished building materials where marking would require rework or rejection.

Compatible Materials

• Coated and treated flat glass (low-e, reflective, decorative coatings)
• Polished granite, marble, and engineered stone (flat)
• High-gloss and finished architectural glass panels (flat)
• Painted, powder-coated, and finished metal panels (flat)
• Tempered and laminated safety glass with sensitive coatings (flat)
• Any smooth, nonporous flat surface where marking from standard rubber pads is unacceptable, with load ≤ 125 lbs

Not compatible with: curved surfaces (flat only); rough, textured, or porous surfaces; surfaces contaminated with oil, wax, or debris — note that pad contamination can transfer to sensitive surfaces and must be avoided.

Application Instructions

Step 1: Pad Inspection and Cleanliness

1. Inspect the VPFS8L low-marking pad for contamination, cuts, or damage. A contaminated pad can transfer residue to the sensitive surface — clean the pad face before every lift on a sensitive surface.
2. Use only clean, lint-free materials to clean the pad face — avoid solvents that may degrade the low-marking rubber compound.

Step 2: Surface Assessment

1. Confirm the surface is smooth, flat, and nonporous.
2. Clean the pad contact area on the workpiece — remove dust, oil, and debris that could contaminate the low-marking pad or transfer to adjacent surfaces.
3. Verify the load weight does not exceed 125 lbs (57 kg).

Step 3: Attaching the Cup

1. Position the pad flat against the surface with full perimeter contact across the 8" diameter.
2. Engage the vacuum mechanism using the plastic handle/plunger until firm resistance is felt.
3. Check the red-line vacuum indicator — confirm a stable, full vacuum before lifting.
4. Apply a controlled test load to verify seal integrity before committing to the full lift.

Step 4: Lifting and Release

1. Lift smoothly — avoid sudden jerking motions.
2. Monitor the red-line indicator continuously throughout the lift.
3. Do not exceed the 125 lb (57 kg) rated load capacity.
4. Lower the load fully to a stable surface before releasing the vacuum.
5. Clean the pad after use and store in the supplied protective carrying case.

Frequently Asked Questions

Q: What is the difference between the N4000LLM and the standard N4000?
A: Both are 8" flat-surface cups with 125 lb capacity. The N4000LLM uses the VPFS8L low-marking rubber pad and all-plastic handle/plunger, specifically designed to avoid leaving marks or stains on sensitive surfaces. The standard N4000 uses the G0695 standard rubber pad and all-metal handle/plunger. Choose the N4000LLM when surface marking from standard rubber is unacceptable; choose the N4000 for standard flat-surface applications where marking is not a concern. The VPFS8L and G0695 pads are not interchangeable.

Q: Does the low-marking pad completely eliminate all marking?
A: The VPFS8L low-marking rubber compound is specifically formulated to minimize marks and stains compared to standard rubber pads. However, pad cleanliness is critical — a contaminated low-marking pad can still transfer residue to a sensitive surface. Always inspect and clean the pad face before each lift on a sensitive surface.

Q: What replacement pad does the N4000LLM use?
A: The N4000LLM uses the VPFS8L low-marking rubber pad (8" diameter). This is a different pad from the G0695 (standard N4000) — do not substitute a G0695 pad. Replacement VPFS8L pads are available separately through Wood’s Powr-Grip authorized distributors.

Q: Is this product made to order?
A: Yes. This product is made to order and all sales are final. Please confirm your surface type and load requirements before placing your order.
