4-½” Mounting Cup with Cleat Head - Pack of 4

Wood's Powr-Grip LJ45PHC — 4-1/2" Vacuum Mounting Cup with Fully Adjustable Pan-and-Tilt Head for Cameras and Video Cameras — Pack of 4

The Wood's Powr-Grip LJ45PHC is a 4-1/2" vacuum mounting cup with a fully adjustable pan-and-tilt head and a 1/4-20 threaded stud on an adjustable arm — the standard camera and video camera tripod thread — designed to provide a reliable, temporary mounting point for cameras and video cameras on smooth, nonporous surfaces without drilling holes or permanently modifying the surface. The pan-and-tilt head allows the camera to be precisely aimed and repositioned after the cup is attached to the surface, enabling flexible camera placement on vehicle glass, architectural glass, polished stone, and other smooth nonporous flat or curved surfaces. Featuring a 4-1/2" (11 cm) LJ45 standard rubber suction pad, variable mounting platform height (adjustable arm), and rated for both flat and curved surfaces with a minimum radius of 12" (305 mm). Operable down to 0°F (-18°C). Sold as a Pack of 4 with vacuum pad protectors. The LJ45PHC (SKU: 91244, Model: LJ45PHC) is manufactured by Wood's Powr-Grip.

The LJ45PHC is a camera mounting cup, not a general equipment mounting cup and not a RAM®-compatible ball cup. The 1/4-20 threaded stud is the universal camera and video camera tripod thread, making the LJ45PHC directly compatible with cameras, video cameras, and accessories that use the standard 1/4-20 camera mount thread. The fully adjustable pan-and-tilt head allows the camera angle to be set independently of the cup attachment position — enabling precise camera aiming on surfaces where the cup must be placed in a fixed location but the camera direction needs to be adjusted.

Key Features & Benefits

Fully Adjustable Pan-and-Tilt Head — Precise Camera Aiming After Surface Attachment

The LJ45PHC’s pan-and-tilt head allows the camera to be panned (rotated horizontally) and tilted (angled vertically) after the cup is attached to the surface. This decouples camera aiming from cup placement — the cup can be attached at the optimal vacuum location on the surface, and the camera angle can then be adjusted independently for precise framing. This is the critical functional advantage over fixed-stud mounting cups for camera applications.

1/4-20 Threaded Stud — Universal Camera and Video Camera Tripod Thread

The 1/4-20 threaded stud is the universal standard thread used on camera tripods, ball heads, and camera accessories worldwide. This makes the LJ45PHC directly compatible with cameras, video cameras, action cameras with 1/4-20 adapters, and a wide range of camera accessories without requiring additional adapters. The stud is mounted on an adjustable arm, providing variable mounting platform height to accommodate different camera body sizes and lens configurations.

No-Drill Camera Mounting — No Surface Damage — Repositionable

The LJ45PHC eliminates the need for drilling holes when mounting cameras on smooth nonporous surfaces. The vacuum cup base attaches without permanent modification, leaving no marks or damage when removed. The cup can be repositioned as needed for different shooting angles and locations.

4-1/2" LJ45 Pad — Flat and Curved Surfaces — Min. 12" Radius — Variable Height

Uses the 4-1/2" (11 cm) LJ45 standard rubber pad for reliable vacuum attachment on flat and curved smooth, nonporous surfaces with a minimum radius of 12" (305 mm) — covering vehicle windshields, curved architectural glass, and curved stone surfaces. Mounting platform height is variable (adjustable arm). Red-line indicator warns of any significant vacuum loss. Rated for operation down to 0°F (-18°C). Pack of 4 with vacuum pad protectors.

Common Applications

Vehicle Glass Camera Mounting — Film and Video Production

Film and video production crews use the LJ45PHC to mount cameras on vehicle windshields, side windows, and rear glass for in-vehicle and chase vehicle shots without drilling into the vehicle. The pan-and-tilt head allows precise camera aiming after the cup is attached to the glass, and the 12" minimum radius covers the majority of automotive glass curvatures.

Architectural and Construction Documentation

Photographers and videographers documenting architectural projects, construction progress, and building inspections use the LJ45PHC to mount cameras on glass panels, polished stone, and smooth architectural surfaces for fixed-position time-lapse and documentation shots without surface modification.

Security and Surveillance Camera Temporary Mounting

Security professionals use the LJ45PHC to temporarily mount cameras on smooth nonporous surfaces for surveillance, monitoring, and inspection setups where permanent installation is not permitted or practical.

Industrial and Scientific Camera Mounting

Engineers and technicians use the LJ45PHC to mount cameras and video cameras on smooth nonporous surfaces for process monitoring, quality inspection, and scientific documentation where a repositionable, no-drill camera mount is required.

Compatible Surfaces

• Flat and curved plate glass and float glass (min. 12" radius)
• Tempered and laminated safety glass (flat and curved)
• Vehicle windshields and automotive glass (flat and curved, min. 12" radius)
• Polished granite, marble, and engineered stone (flat and curved)
• Smooth painted or coated metal panels (flat and curved)
• Any smooth, nonporous flat or curved surface with min. 12" (305 mm) radius

Not compatible with: rough, textured, or porous surfaces; surfaces with radius tighter than 12" (305 mm); surfaces contaminated with oil, wax, or debris; applications requiring permanent camera mounting.

Technical Specifications

Safety Data Summary

• Vacuum loss can result in sudden camera drop or detachment — monitor the red-line indicator during use; never position personnel or equipment below a vacuum-mounted camera
• 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 on surfaces with radius tighter than 12" (305 mm)
• Do not use for permanent camera mounting applications
• Damaged or contaminated pads must be replaced before use
• Operating below 0°F (-18°C) may degrade rubber pad performance

Frequently Asked Questions

Q: What cameras are compatible with the LJ45PHC?
A: The LJ45PHC uses a 1/4-20 threaded stud — the universal standard camera tripod thread. This is compatible with the majority of cameras, video cameras, and camera accessories that use the standard 1/4-20 camera mount thread, including DSLRs, mirrorless cameras, video cameras, and action cameras with 1/4-20 adapters. Verify your camera’s tripod thread specification before ordering.

Q: What is the difference between the LJ45PHC and the RAM®-compatible mounting cups (TL6PB1, LJ45PB1, TL3PB1)?
A: The LJ45PHC uses a 1/4-20 threaded stud on a fully adjustable pan-and-tilt head — specifically designed for cameras and video cameras using the standard camera tripod thread. The RAM®-compatible cups (TL6PB1, LJ45PB1, TL3PB1) use a 1" RAM® ball for attaching RAM® arms and accessories. Choose the LJ45PHC for direct camera mounting with pan-and-tilt adjustment; choose a RAM® ball cup for RAM® system compatibility.

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: Is this product made to order?
A: Yes. This product is made to order and all sales are final. Please confirm your surface type, curvature radius, and camera compatibility before placing your order.
