Slip On Stop Collar (Ring) with Set Screws
Stop collar (Stop ring) is used to fix the centralizer on the casing and prevent centralizers moving up and down.
Slip on stop collar with set screws (set screw stop ring) is made of a single piece collar with one or two rows of set screws to induce the gripping force. It is designed for use where higher holding forces are required. It has reliable holding force, and it is more robust than the latch-on type.
The sizes from 4 1/2 to 20 inches are available.
When ordering, please specify:
