solution: simply a hard black anodized and teflon coated aluminium frame in one piece.
A complete range from 60 to 140 mm sheaves in single, double, triple, fiddle, and deck versions,
for webbing or shackle connection. Sizes are based on the range of HR shackles available and on
their safe working load (SWL).
THE HR SWIVEL HEAD

transversal lock. HR shackles included
THE ONE-PIECE FRAME
The one-piece aluminium extruded body is the strongest and lightest solution, no assembling pin
rivets or screws and nuts.
CNC machined - polished - hard black anodized and teflon coated.
THE COMPOSITE FIBRE SHEAVE
The resin (aluminium on larger mod) sheave runs on the main Composite Fibre bearing and on a ground
s.steel hub: low friction highloads - no lubricant required.

maintenance very easy.
