Spring-Fin P-Clamp For 18-24 mm Pipe
A one-piece P-clamp with a 29 mm split ring lined with five flexible spring fins. It grips 1/2 in EMT (17.9 mm), 1/2 in PVC (21.3 mm) or 3/4 in EMT (23.4 mm) without rattling, so you don't have to buy a box of 25 fixed-size clamps to get one odd size. Two 5.5 mm screw holes, 54 mm apart, take #8/#10 wood screws or M5 bolts into a stud or frame rail. Tightening the screw through the 14 mm wide strap closes the 4 mm tab gap and squeezes the ring onto the pipe. Thread the clamp onto the run before you fix it.
