Soft attachment
More Information
A strop soft-attach is fixed on one side, but is easily removable on the other.
The strop carries the block’s primary load and articulates for a fairlead.
The Velcro® strap is permanently attached to one side plate and holds the block securely closed when side plates are aligned—even under the highest loads.
The strap has a broad reflective tab for easier operation with gloves.
Harken composite bearing technology (ULC) ensures sheaves turn smoothly and maintain efficiency under extreme loading.
Snap-fit Torlon® bearings carry sideloads. An integral headspacer prevents Hard Lube-anodized Aluminium side plates from deflecting and binding.
The wide sheave allows a range of line diameters.
