Stop Collar
A single piece collar with the set screws on the outer circle of the periphery, which is meant for installing and is directly installed on the pipe by slipping on the casing. Fabricated using ductile iron, which gives it good impact and fatigue capabilities. Used in places where high axial loads are expected.

Stop Collar
A single piece collar that uses one row of set screws to induce the gripping force. Used where high axial loads are expected and effective where low annular clearance is encountered. Easily slides onto casing, making installing the stop collar incredibly easy.
Hinged Set Screw
Stop Collar
Made up of two pieces and hinged at both ends. The gripping force is applied by one row of set screws, tightening the collar to the casing firmly. The stop collars can be fastened on to the casing joint and are most effective in conditions where there is low annular clearance.
