Stop collar (Stop ring) is used to fix the centralizer on the casing and prevent centralizers moving up and down.
The following stop collars (stop rings) are available:

Slip on stop collar with set screws

 

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.

 

Hinged stop collar with bolt

 

Hinged (latch type) stop collar with bolt is used in most type of well designs. It can be used with most hinged bow centralizers. It allows quick and easy installation over casing.

 

Hinged stop collar with spiral nails
