Selden High Load Ball Bearing Stainless Jib Sheave Box

The Selden range of sheave boxes cover all requirements, from standard jib, spinnaker and topping lifti sheave boxes to lower halyard exit sheaves. 

The standard sheave box is manufactured from a high-load composite material offering the ultimate in strength, weight and performance.  The new high-load sheave box is the most recent development.  Manufactured from cast stainless steel, it is a low profile sheave box that can take a very high line load.  It is ideal for applications such as the Flying Dutchman jib sheave box.

Both ball bearing and plain sheaves are available and they are easily inter-changeable between our jib and halyard exit boxes.  Both sheaves are suitable for either wire or rope line.  Stainless steel spinnaker and pole lift box is supplied with a ball bearing sheave as standard.

Wear guards have been developed to protect the sides of the sheave box where the line entering the box is off-axis (as with spinnaker halyards and pole lifts).
