Low profile, light weight blocks are incredibly strong. Typically used as primary lead blocks on dinghies and catamarans, they are also suitable for many control line applications on larger boats. Ronstan's two-stage ball bearing system provides consistent performance over the full load range of the blocks. The block cheeks are fiber reinforced Zytel. Load straps and head fittings are 316 stainless, Acetal ball bearings, and UV stabilized Acetal sheaves. Sheave Dia.: 1-3/16" (30mm). Max. Rope: 5/16" (8mm).
