The same strength and control available to the day-sailor and one-design skipper, makes this extensive selection of strong, high quality fittings also ideal as control blocks on larger racing 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 white Delrin (TM), and turn on polished, stainless steel spacers that prevent the cheeks from squeezing and binding the sheave, even under heavy loads.
