Cam Handles

Use these standard cam handles for most clamping applications. Push down on the handle and the head applies pressure to quickly draw two parts together for fast adjustments.

Threaded-Hole Mount

Threaded-hole handles install on a threaded stud.

Powder-Coated Aluminum Handle—Powder-coated aluminum handles have mild corrosion resistance, are lightweight, and are nonmagnetic.

316 Stainless Steel Handle—316 stainless steel handles have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

Clamping Distance—Clamping distance is how far the handle will draw parts together when clamped.
