After years of research and testing we’ve built what we consider the best shop clamp made. It’s smooth, versatile and built to stand up to everyday shop use.
• Fits PCS-4, PRS-7, some models of PRS-5 (with composite top tubes), and PCS-1 models manufacturer post 2002. (Note: Inspect top tube below lever for an embossed "939")
• Cam-actuated adjustment system for quick entry, adjustment and exit
• Narrow clamping jaws (2.7”/7cm) designed to clamp securely yet fit into tight areas or on short seat posts.
Fully adjustable clamping pressure prevents damage to thin-walled tubes
