Schaefer Twin Sheet Lead Blocks feature a side-to-side pivoting extra wide sheave and cage design that allows for the passage of two jib sheets simultaneously. These blocks are ideal on racing boats to allow for quick sail changes. Their low profile design keeps sheets close to the deck for proper lead to deck mounted winches.
Constructed of heavy-duty, black anodized aluminum with sheaves that feature NTE Nomex/Teflon bearings. Spring pin stops allow quick adjustment for changing wind conditions.
