Cos’s Hinged Bolted Stop Collar is a single piece collar and the set crews are provided on the outer circle of the periphery which is meant for installing and is directly installed on the pipe by slipping on the casing without any hassle. It is fabricated using ductile iron therefore it has a good impact and fatigue capability. These kinds of collars are used in place where high axial loads are expected.

This works well in the installation of different cement baskets and various types of centralizers

These are available in 2 7/8" to 30 " sizes.
