The FastGun turnbuckle is the most popular truck camper turnbuckle for several reasons. It’s tool-free, lockable, easy to adjust and snaps into place with the perfect amount of tension every time. With this simple trick, achieve the quick-disconnect capability and convenience of a FastGun turnbuckle with any basic hardware turnbuckle.

Solution: Derringer Handle
Transform old-fashion turnbuckles by adding a Derringer Handle to a basic turnbuckle chain system, standard chainless turnbuckles and even shorter length turnbuckles for bed-mounted applications. This allows for the lever action and ease of use that Torklift International FastGun turnbuckles provide. The Derringer Handle is applicable to chain systems, threaded rods and other rigging configurations.


Derringer handles for quick-disconnect capability

#1) Basic chain system
If you are currently using Torklift’s Basic SpringLoad Kit or a similar design, the Derringer Handle is attached with minimal effort.

Attach a Derringer Handle to chain turnbuckles using the following steps:

• Locate the drop forged steel and hot dipped galvanized eyebolts that come with each Derringer Handle
• Attach the eyebolts to each Derringer Handle by tightening it with a washer and lock nut combination (see instructions for eyebolt assembly)
• Use the hook-to-hook turnbuckle and attach through the bottom of Derringer Handle
• Secure hook bolt on Derringer Handle to the camper anchor point and tighten turnbuckles accordingly

#2) Threaded rod
If you are currently using a SpringLoad XL, AnchorGuard turnbuckle or a similar design with a 1/2 inch threaded rod, the Derringer Handle is attached in two ways. Either use the eyebolt configuration as described above by hanging each turnbuckle hook bolt through the eyebolts, or create one turnbuckle unit by fastening the Derringer Handle onto a 1/2 inch threaded rod. To achieve a turnbuckle design similar to the Torklift FastGun, Torklift suggests this method of permanently bolting the Derringer Handle to the rod, creating one unit.

Attach a Derringer Handle to a 1/2 inch threaded rod using the following steps:

• To hold the rod in place, use a wrench to tighten a jam nut to the body of the turnbuckle
• Where the threading starts, use a hacksaw and cut the rod. Bevel the top of the rod at 45 degrees using a sander, grinder or file -- Bonus Tip: Apply a small amount of paint to the newly cut end of the threaded rod to prevent corrosion
• Add a turnbuckle jam nut and adjust 5 inches from the top of the newly cut rod
• Open the Derringer Handle and insert the threaded rod through the hole in the bottom of the Derringer Handle, screw on dimple nut and tighten down
• Adjust threaded rod so 1/8 inch protrudes from the top of the dimple nut
• Pull the rod down until the nut is snug to the bottom of the handle
• Tighten the original jam nut (the one 5 inches down) to the bottom of the Derringer Handle
