3" Mounting Cup - Pack of 4

Wood's Powr-Grip TL3AMB — 3" UV-Resistant Vacuum Mounting Cup for Flat and Curved Surfaces — Pack of 4

The Wood's Powr-Grip TL3AMB is a compact 3" (8 cm) vacuum mounting cup designed to provide a reliable, temporary mounting point for equipment on smooth, nonporous surfaces — without drilling holes, marking, or damaging the surface. Featuring a 3" UV-resistant rubber suction pad (Model TL3), a threaded stud or tap for equipment attachment, and a red-line vacuum indicator, the TL3AMB mounts tools, fixtures, sensors, brackets, and other equipment to flat and curved smooth nonporous surfaces quickly and without permanent modification. Rated for both flat and curved surfaces, operable down to 0°F (-18°C). Sold as a Pack of 4 with pad protectors. Available in multiple threaded stud configurations — select the thread size that matches your equipment mounting requirement. The TL3AMB (Model: TL3AMB) is manufactured by Wood's Powr-Grip.

The TL3AMB is a mounting cup, not a hand cup — it is designed to attach equipment to a surface rather than to lift and carry loads. The threaded stud or tap on the cup body accepts bolts, brackets, and fixtures, allowing the cup to serve as a temporary vacuum-mounted anchor point. Load capacity varies by application and surface conditions — see the WPG Mounting Cup Capacity Calculator for application-specific capacity guidance. Other stud lengths and thread configurations are available beyond the standard variants listed.

Key Features & Benefits

No-Drill Temporary Equipment Mounting — No Surface Damage

The TL3AMB eliminates the need for drilling holes when mounting equipment to smooth, nonporous surfaces. The vacuum cup provides a temporary, removable mounting point that leaves no permanent marks or damage when removed — making it suitable for rental equipment, temporary fixtures, production line tooling, and any application where permanent surface modification is not permitted or practical.

UV-Resistant Rubber Pad (Model TL3) — Flat and Curved Surfaces

The TL3 pad uses UV-resistant rubber, providing extended service life in outdoor and UV-exposed environments compared to standard rubber pads. Rated for both flat and curved smooth, nonporous surfaces. The UV-resistant compound resists degradation from sunlight exposure, making the TL3AMB suitable for outdoor mounting applications where standard rubber pads would degrade more rapidly.

Multiple Threaded Stud Configurations — Select to Match Your Equipment

The TL3AMB is available in four configurations to match different equipment mounting requirements:

• 1/4"-20 x 5/8" Threaded Stud (SKU: 91152) — standard short stud for direct equipment attachment
• 1/4"-20 x 3/8" Threaded Stud (SKU: 91150) — shorter stud for low-profile mounting
• 1/4"-20 x 1-1/4" Threaded Stud (SKU: 91153) — longer stud for deeper clearance requirements
• No Stud or Tap (SKU: 91156) — plain cup body for custom mounting configurations

Other stud lengths and thread configurations are available — contact Wood's Powr-Grip or your authorized distributor for non-standard configurations.

Red-Line Vacuum Indicator — Pad Protector Included — Pack of 4

The red-line indicator warns of any significant vacuum loss during use. Each cup ships with a pad protector to prevent damage to the TL3 pad during storage and transport. Sold as a Pack of 4.

Common Applications

Temporary Tool and Fixture Mounting

Fabricators, machinists, and production operators use the TL3AMB to mount tools, fixtures, clamps, and work-holding devices to smooth nonporous surfaces without drilling. The vacuum cup provides a stable, repositionable mounting point that can be moved as production requirements change.

Sensor and Instrument Mounting

Technicians and engineers use the TL3AMB to mount sensors, gauges, cameras, and instruments to smooth surfaces for temporary measurement, monitoring, or inspection setups without permanent installation.

Outdoor and UV-Exposed Environments

The UV-resistant TL3 pad makes the TL3AMB suitable for outdoor mounting applications — including vehicle glass, outdoor signage surfaces, and exterior architectural glass — where standard rubber pads would degrade from UV exposure.

No-Drill Equipment Mounting on Protected Surfaces

In environments where drilling is not permitted — including leased spaces, historic buildings, finished architectural surfaces, and cleanroom environments — the TL3AMB provides a temporary mounting solution that leaves no permanent modification.

Compatible Surfaces

• Flat and curved plate glass and float glass
• Tempered and laminated safety glass (flat and curved)
• Polished stone and engineered stone (flat and curved)
• Smooth painted or coated metal panels (flat and curved)
• Vehicle glass and automotive surfaces (flat and curved)
• Any smooth, nonporous flat or curved surface suitable for vacuum attachment

Not compatible with: rough, textured, or porous surfaces; surfaces contaminated with oil, wax, or debris; applications requiring permanent load-bearing attachment.

Technical Specifications

Safety Data Summary

• Vacuum loss can result in sudden equipment drop or detachment — monitor the red-line indicator during use
• Load capacity is application-dependent — use the WPG Mounting Cup Capacity Calculator to determine safe working load for your specific application and surface
• Do not use on rough, textured, or porous surfaces
• Do not use for permanent load-bearing applications — this is a temporary mounting solution
• Damaged or contaminated pads must be replaced before use
• Do not use above 5,000 ft (1,500 m) elevation

Frequently Asked Questions

Q: How do I determine the load capacity for my application?
A: Load capacity for mounting cups varies by application, surface conditions, and orientation. Use the Wood's Powr-Grip Mounting Cup Capacity Calculator to determine the safe working load for your specific setup.

Q: Which stud configuration should I select?
A: Select the stud length and thread that matches your equipment mounting hardware. The 1/4"-20 thread is standard across all stud variants. Choose the stud length based on the clearance required between the cup body and your equipment bracket or fixture. If none of the standard configurations match your requirement, other stud lengths and thread configurations are available — contact Wood’s Powr-Grip or your authorized distributor.

Q: Why does the TL3AMB use UV-resistant rubber instead of standard rubber?
A: The UV-resistant TL3 pad is designed for applications with UV exposure — including outdoor mounting, vehicle glass, and exterior architectural surfaces — where standard rubber pads would degrade more rapidly from sunlight. The UV-resistant compound extends pad service life in these environments.

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, stud configuration, and application requirements before placing your order.
