Rockler 3-Way Face Clamp - Adjustable Clamp for Cabinet Carcass & Edging Shelves – Lightweight Clamps Heavy Duty for Face Frames – Woodworking Clamps Opens to Clear 5" or 3" Wide Frame;

These exceptionally adjustable clamps are especially well-suited for clamping face frames to the cabinet carcass, and for edging shelves. Since they clamp to the front edge of the panels, the sky is the limit when it comes to cabinet depth, and they'll work even when the cabinet back is already attached. With quick-release acme threads, it's easy to adjust the clamp to wrap around wide stiles, whether the panel is flush with the edge of the frame or not. Non-marring pads ensure you won't dent the frames in the process. Light weight and compact, they're easy to move around and store. Clamp opens enough to clear a 5" wide frame (panel centered) or 3" wide frame (panel flush with edge). Patent Pending.
