F Series Center Punch Clamp, 3.50 Inch Clamp ID, Inch Width, 0.031 Inch Thick

For a preformed clamp at that diameter, the 5/8-inch band width does its job. The center punch design locks the band in place during tightening, which keeps it from shifting once it's seated. The galvanized steel construction adds rigidity to the band itself, so you're not dealing with a flimsy strip that'll deform under load. That combination of preformed shape and punch mechanism is what gives it staying power on a 3.5-inch application.

The key number on this clamp is the 3.50 inch clamp ID, so it matches an inside diameter of 3 1/2 inches.

This clamp is made from galvanized steel, which offers a good balance of strength and corrosion resistance for general industrial use.
