Series 8 blocks have stainless steel cheeks and Series 9 blocks have black aluminum cheeks. They offer the high strength and low friction needed to bridge the gap between medium-sized racing or cruising yachts and larger offshore designs. These are the blocks to have when you sail to remote locations where trouble-free performance is paramount. They feature bolted construction, so they can be easily disassembled for maintenance or parts replacement.
Line-only models come with Delrin® sheaves and a friction-reducing, Teflon® impregnated bushing. UC models feature Universal Circuit Sheaves that are among the smoothest spinning sheaves available. They incorporate an aluminum alloy sheave for high-tech lines or wire, slippery Nomex/Teflon® bushings and dual races of Delrin® 107 ball bearings. They are precision engineered to withstand heavy static loads on the Nomex® bearing, yet still run free on the ball bearings when lightly loaded
