Setup Clamp Supports
Keep setup clamps from falling out of position when they are unclamped—the spring holds them up for quick workpiece insertion and removal. Slide the support over your T-slot bolt or stud and lock in place by tightening the set screw on the collar. Also known as spring lifters.
Side Clamps
Standard
Low Profile
Standard
Low Profile
Grip the side of a workpiece to leave the top free for machining. These clamps exert force both forward and downward when tightened. Secure to your machine table with a screw, nut, and stud (not included), and then tighten the set screw in the body of the clamp to push the serrated jaw out and against the side of your workpiece. Also known as toe clamps.
Low-profile clamps have a small contact area for more access to your workpiece.
Aluminum jaw caps can be placed over the jaw to prevent damage to workpieces.

T-Slot Side Clamps
The built-in T-slot nut on these side clamps lets you clamp a part to a machine table quickly. Their small footprint leaves more free space on your table than standard side clamps. When tightened, these clamps exert forward and downward force on the workpiece from the side, leaving the top free for machining.
