Ace Ratchet Collar Slim

Delivering unrivalled holding force under all operating conditions the ARC-Slim is the first 90,000lb+ rated stop collar on the market.  Uniquely designed, ARC-Slim mounts downhole accessories directly to the outside of the casing or completion string.

The patented 2-piece collar uses our proprietary ratchet
mechanism, press fitting the two sets of ratchets together to permanently lock the collar to the casing. Without a complex installation process or tool with troublesome set screws ARC-Slim delivers an extremely high holding force under all operating conditions, with no impact on drift.

The core of our family of products the ARC-Slim can also be used with any 3rd party centralizer or casing accessory. The ARC-Slim performs as a stop collar to hold both solid body and bow spring centralizers or other accessories on casing or liner.

The ARC-Slim can be taken directly from the shelf and installed onto any size and grade API pipe in yield strength up to 140ksi. Available for standard clearance and close-tolerance applications, the ARC-Slim is manufactured from 4140 steel or chrome materials. Non-standard sizes or materials are also available upon request.
