Overview

The Induro 490-050 QRT50 Quick Release Clamp is a practical accessory for photographers who need a reliable way to attach and detach cameras quickly from their tripod or monopod. Built around an Arca-Swiss compatible dovetail system, it accepts plates from a wide range of manufacturers, giving you flexibility across your gear collection. The twist-lock mechanism provides a secure grip on the plate, while the double-action safety lock adds a critical second layer of protection against accidental release — a feature that matters most when expensive camera bodies and lenses are on the line.

Mounting is straightforward thanks to dual-thread compatibility with both 1/4-20 and 3/8-16 screws, which means the QRT50 can be fitted to virtually any standard tripod head. Originally designed for Benro support systems, it integrates seamlessly with other brands as well. The clamp's machined construction feels solid without adding excessive weight to your rig, making it a sensible upgrade for anyone looking to move to an Arca-Swiss workflow or replace a worn-out proprietary quick release system.
