Allen Brothers 180 Degree Mast Swivel Cleat With Removable Sheave
Allen Brothers 180 Degree Mast Swivel Cleat With Removable Sheave
30mm Dynamic Lightweight Flip Flop Block With Removable Sheave
Flip Flop Blocks are designed to pivot around a central fixing point, keeping the rope close to the deck, mast or boom while still allowing the block to articulate to the correct lead angle. This helps minimise friction while guiding the rope efficiently.
This lightweight version features a nylon body and nylon backing plate to keep both weight and cost to a minimum.
30mm Dynamic Bearing Sheave
Features a 30mm Dynamic Bearing sheave, using twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides superior load-carrying capability and longevity compared to bearing systems that run on plastic rails.
The sheave can be moved to one of the two locations. Allowing for rope to enter from above or below.
Allenite Cam Cleat
Fitted with the A.677 small Allenite cam cleat. Allenite is a material developed by Allen to provide low weight and excellent heat dissipation, increasing wear resistance compared to standard acetals. The Allenite cam cleat also offers a significant weight saving over the aluminium version.
Applications
Ideal for lower-load applications such as:
- Halyards
- Pole launchers
- Jib sheets
For higher-load applications, we recommend using the A2133-77.
