Allen 20mm Triple Articulating Block Select (See Table Below):AL-2024-A 20MM DYNAMIC: TRP ARTICULATING - EACH 15HP HE15KCF 1997 Engine Cover20mm Triple Articulating Block This triple articulating block is very similar to the standard triple except the central rivet and spacing mouldings have been removed. Each block can articulate to the correct lead angle allowing the rope to run more centrally around the sheaves. The result is a reduction in friction as well as making the block last longer due to less wear on the cheeks. Blocks articulate individually Allows better alignment to rope
