New Product Announcements From: 9/17/2007 Modern Machine Shop Carr Lane Mfg. Co. has expanded its low-profile, T-handle toggle clamp line to include two larger clamps in both steel and stainless steel. All three sizes (CL-200-LVTC, CL-300-LVTC and CL-500-LVTC) are available with an optional safety lock that automatically engages when the clamp is closed. It remains locked until it is manually disengaged by pushing a lever. This prevents the clamp from being opened accidentally by bumping the handle. These vertical-handle clamps have holding capacities ranging from 150 to 750 lbs.
