Harken 6050 57 mm Aluminum Mast Collar ESP Block

ESP Blocks are a special line of hardware that compliments the existing Harken block line but is simpler in design and construction.

Sheaves have an axle bearing for high static loads and are ideal for situations where the block's primary function is to change the direction of a statically loaded line such as halyards on production boats or cruiser/racers.

Contained ball bearings handle side loads so blocks spin freely when loads are released.

  • Sheave Ø 2-1/4" (57 mm)
  • Length 3-11/16" (93.5 mm)
  • Weight 4.3 oz (122 g)
  • Clevis pin Ø 5/16" (8 mm)
  • Maximum line Ø 5/8" (16 mm)
  • Maximum working load 2,100 lb (850 kg)
  • Breaking load 4,190 lb (1900 kg)
