This rugged, "offshore" design provides a low winch lead while spreading sheet loads over several track fasteners for maximum strength. Set pin location in the center of the block prevents snagging and accidental release. Designed to articulate up to 45° to either side of the track, Half-Moon lead blocks are often used to provide a proper lead angle to foot or turning blocks near the cockpit. Stainless, bolted construction provides a brilliant finish, and allows complete disassembly for inspection or maintenance
