Synchro Footblock with Jammer

Lewmar’s Synchro Footblocks are built for durability, precision, and ease of use. Featuring tough alloy cheeks, twin fixings with isolator inserts, and a moulded base plate, they’re designed to prevent sealant ingress into the sheave and ensure a secure, long-lasting installation.

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.

• Standard and Jamming Options – Both can be double-stacked for versatile rigging setups.
• Optimised Jammer Shape – Keeps the line centred on the sheave for consistent performance.
• Robust Alloy Cheeks – Provide strength and resistance to wear.
• Synchro Sheave Load Ratings – Match those of equivalent-sized blocks for seamless integration.
• Twin Fixings with Inserts – Ensure secure mounting and reduce stress on deck fittings.
• Wide Head Design – Offers a stable base that prevents the block from rolling on deck.
• Moulded Base Plate – Includes a recessed area to hold sealant around fixings and screws, protecting the bearing and sheave from ingress.
