Hinged Bolted Stop Collars

Hinged bolted stop collar is intended to lock on the casing without being slipped over the casing and offers quick and easy installation. It has higher holding forces than the centralizer starting force.

It utilizes a nut-bolt assembly to fix together and draws the stop collar into a friction grip around the perimeter of the casing.
