The low profile range of sheave boxes feature Allen's unique hook-in cage; designed to deal with the high loads of modern rigs.

Schaefer's halyard exit boxes feature Stainless Steel construction with aluminum sheaves and Stainless Steel spacers with the ability to handle high static halyard and reefing loads.

Antal - 12 different sizes with diameters from 40 to 140 mm for working loads (SWL) up to 9000 kg. Hard black anodized aluminium frame with insulating washers for corrosion protection. Resin sheaves (aluminium sheaves for 100, 120 and 140 mm only) with composite fibre main bearing (not on size 40) and double side self-captive ball bearing (mounting screws not included)
