Instant Hoist Cleat:
One Mini RopeTie instantly transforms a 3 to 1 block and tackle system into a 5 to 1 with self cleating feature that allows one hand operation. The effort of keeping a load after hoisting is taken by the RopeTie and the load will not be dropped when the operator releases the rope. Most people will not need this for hoisting a 30 lb battery but it works with loads up to 250 lbs, and will enable a person with limited use of one hand. Cost: under $6.
