Description
Lewmar 90mm Synchro Footblocks with Jammer feature alloy cheeks, fixing isolators, and a moulded base plate to prevent sealant ingress into the sheave. Jamming Footblocks are designed to hold light hand loads only.
The jamming footblock variant is intended for light hand loads only and incorporates a clever two-step jammer action that keeps the lever close to the block’s side, maintaining a compact profile and reliable grip.
