Sold in sets of four, the Derringer has been designed to thread easily onto 1/2" threaded rods found on all major truck camper turnbuckle brands. Features of the All-New FastGun Derringer.
Now you can simply cut the hook off of any truck camper turnbuckle that uses a 1/2" 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 (included) to accept any rigging! Derringers are a simple retro fit to the Torklift Springload XL and ACAR turnbuckles as well.
