Hand-polished stainless steel sideplates are the trademark of these beautiful blocks. But it's the sheave design that gives them their strength and durability. Sheaves use a low-friction composite sleeve bearing for extreme radial loads. Ball bearings handle side loads. This proven sheave design is used on super-yachts where blocks must perform under very high, sustained loads without being excessive in size.
Block details include low-profile screw adapters and stainless-on-stainless construction for easy service. Sheaves on foot blocks remove without unbolting the block. Headposts on swivel blocks lock or swivel freely.
