Adjustable Chain Shortener

Adjustable Chain Shortener

The patent pending Adjustable Chain Shortener (ACS-281) is designed to give adjustability to the installed height of a rigging location. [break] The ACS-281 works with Gunnebo-Johnson 9/32 inch Grade 100 heat-treated alloy steel chain that Polar Focus has used for years to provide superior strength and reliability for basket hitch and choker hitch beam connections. The chain feeds through the ACS-281 and when the desired height is reached, the chain is pushed into a slot and held from pulling free by the shackle that is used to connect to the load being suspended. Height adjustment is in 0.82 inch increments. [break] Using the ACS-281 can be particularly beneficial when time constraints of a job do not allow for accurate dimensions of roof attachment and loudspeaker locations. Also see product codes RCSA (basket) and RCCA (choker) for kits including the ACS-281.
