A durable, versatile, easy-to-use clamp built for everyday shop use. Features a cam-actuated micro-adjust clamping system for easy entry and exit, which opens to fit nearly any tube from 23 to 76 mm (7/8" to 3"), including aero tubes. With infinite adjustability, there's no need to worry about accidentally crushing or damaging delicate carbon fiber tubing. Narrow clamping jaws fit into tight areas or onto short seat posts. The 100-3D is built to last, with a powder coated precision-machined die-cast aluminum main body and durable, replaceable jaw covers.
