Frequently Asked Questions

What is the difference between fixed and swing cheek pulleys?
Fixed cheek pulleys have solid, non-opening side plates — the rope must be threaded through during setup. Swing cheek pulleys have a hinged side plate that opens for mid-line attachment. The fixed cheek design is preferred for rope wrench applications where stability is critical.

Looking for a swing cheek version?
