SMALLRIG 2144B Quick Release Clamp for Arca

This compact quick release clamp and plate from SmallRig streamlines mounting for cameras and cages, offering improved Arca Swiss compatibility and secure attachment for run-and-gun shoots or studio setups. It combines a low-weight aluminium build with adjustable tightness and added safety pins, giving photographers and videographers a reliable way to switch gear quickly.

Key Points

The new version resolves previous Arca Swiss compatibility issues and adds two safety pins on the quick release plate to reduce accidental release during movement. Tightness is adjustable by turning a tiny screw on the lever, which helps achieve a snug fit with a wide range of Arca-style plates. Multiple threaded holes on the base expand mounting options for tripods, gimbals and rigs, making it versatile for different support systems.

Technical Specifications

• Name: SmallRig Quick Release Clamp and Plate (New Version)
• Material: aluminium alloy, CNC machined
• Bottom threads: 1/4 inch and 3/8 inch threaded holes
• Included items: 1 plate and clamp, 2 x 1/4 inch screws, 1 x 3/8 inch screw, 2 Allen wrenches
• Additional features: two safety pins, adjustable clamp tightness

Usage Recommendations

Attach the quick release plate to the base of your camera or camera cage using the supplied screws and one of the Allen wrenches. Adjust the clamp tightness by turning the small screw on the lever until the plate locks with minimal play, then verify that the safety pins engage when sliding the plate into the clamp. Use the multiple thread options on the bottom to mount the clamp directly on a tripod head or to integrate it into a larger rig.

Advantages

The lightweight yet tough aluminium construction keeps added weight low while remaining durable and scratch-resistant. According to the manufacturer, CNC cutting provides precision for smoother operation and consistent fit. Two safety pins add an extra layer of security during active use, and the adjustable lever helps the clamp work with most Arca-standard plates. Consider that very unusual or proprietary quick release systems might still require an adapter.
