Ace Ratchet Collar Force

Based upon our foundational ARC technology, the ARC-Force is an ideal, cost-effective solution for non-close tolerance operations.  At 7mm, the collar is small in size and with unrivalled holding force of 50,000lb, it is suitable for most applications worldwide.

The ARC-Force patented collar uses a proprietary ratchet mechanism, press fitting the two sets of ratchets together to permanently lock the collar to the casing.  With zero loose or moving parts and no impact on drift, the ARC-Force is a secure and reliable solution.  It is also available for quick delivery, offering maximum flexibility for projects.
