Harken Stainless Steel Block Stand Up Cat. No. HAR 31SU Weight 5 lbs

Stainless Steel Stand Up Block 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 footblocks remove without unbolting the block. Headposts on swivel blocks lock or swivel freely. Description Stand-up 3138 Stand-up 3152 Stand-up 3182 Sheave dia.
