An absolute must when rigging aircraft cables. This tool saves time and lets you adjust turnbuckles without the need of an extra hand. The 2" diameter turnbuckle wrench easily rotates the turnbuckle while the chain tool holds the cable ends in precise alignment and prevents them from rotating. Works on all 1/16" to 1/4" cables having MS thimbles or equivelant on any size aircraft. Made of anodized aluminum with steel holding pins.
