Review on Quick Fist Clamp Mounting Equipment Industrial Power & Hand Tools in Workholding by David Alvarez

This. GIGANTIC. While the description says it holds up to 4.5 inches, the product itself is gargantuan. I have had great luck with QuickFist products in the past (many of them have even been used outdoors in the Las Vegas sun for years) and this seems to be another of their well made products. However, they are only very large (wish I had measured them before returning them) but they were too large for my use. 5 stars though. The Quick Fists Rule.
