Derringer Handle transforms your old fashion turnbuckles into quick disconnect lever action turnbuckles. The galvanized eye allows you to connect to any other types of rigging, such as chain, for a quick disconnect turnbuckle. Threads onto ½ Inch threaded rods or adapts to any eyebolt turnbuckle. Now you can simply cut the hook off of any truck camper turnbuckle that uses a 1/2 Inch threaded rod and thread on the FastGun Derringer. Or for an alternative method of installation for conventional hardware turnbuckle users, the Derringer can simply be fitted with a threaded eye to accept any rigging! Derringers are a simple retro fit to the Torklift Springload XL.
