Dynamic and High Static Load Performance
UV stabilised Acetal sheaves provide bearing performance on a polished Stainless Steel race that
performs equally well with dynamic and static loads
Sheave design features side ribs to minimise weight and enhance strength. Self-lubricating
Acetal polymer minimises friction and ensures dependable load bearing reliability.

®
bronze bearing running on the polished
Stainless Steel race to provide the high load capacity required of this range.
Captive Lock™ Universal Head
A simple sliding lock that can be engaged to lock the head post in either of two planes, or
disengaged to allow the block to swivel.
0°/90° 2-Axis Shackle Head
Some double and triple blocks can be locked at 0° or 90° by removing the shackle
and changing the head post orientation.
Keyhole Becket Pins
Becket pins lock into keyhole slots. No tools are required to remove the pins to fit
pre-spliced lines or lock them back into place.
Adjustable Cleat Arms
The angle of the cleat arms can be adjusted easily. Sliding posts are simply
pulled out of the stops to adjust (no tools required), and then snap back
into locked position to secure the arms.
Stainless Steel Cheek Plates and Straps
For ultimate strength and durability Series 60 and 75 AP blocks have grade
316 stainless steel cheek plates and load straps. Cheek plates have a black
chrome finish and are flared at the rope entry and exit points to minimise
rope chafe.
