Schaefer Marine Series 2, 27mm blocks are perfect for vangs, outhauls, backstays, cunninghams and other control blocks on a wide variety of boats.
Cheeks are constructed of tumbled and polished stainless steel for maximum resistance to corrosion and cracking common to other plastic designs. Sheaves are made of tough, high impact Delrin and turned on polished stainless steel spacers that prevent the cheeks from binding the sheave even under heavy load.
