Schaefer's 8 Series Blocks add strength and brilliance to your deck. Featuring Delrin(tm) sheaves, forged stainless steel "D" shackles, bolted construction for strength and Stainless Steel cheeks polished to a high luster.
All 8 series blocks feature Schaefer's high-strength, low-friction Nomex(tm)/Teflon(tm) Bearing that is impervious to water absorption and allows traces of Teflon to flow to the surface reducing friction with use. The combined benefits of this unique design mean more control when you need it most.
Schaefer's "UC" sheave packages add a self-contained circuit of Delrin(tm) ball bearings for a smooth yet strong combination.
