FastCap Knuckle Bender Door Hinge Repair Tool - KB1

The FastCap Knuckle Bender is designed for standard residential doors with standard residential hinges. It is not recommended for commercial, industrial, or custom-designed door hinges.

Typically, the sagging is caused by a bend in one or more knuckles of the hinge. You will need to observe the door and hinges to identify which knuckle is misaligned. Start with the knuckles on the hinge that appears most affected.

No, the tool is designed for ease of use. It has an intuitive design with an integrated pin remover and adjustable grip for bending. However, it's important to apply pressure gradually.

If the sticking is caused by a sagging door due to bent hinge knuckles, yes, this tool can help. If the door sticks due to warping or frame issues, this tool will not resolve that problem.

The tool weighs approximately 314 grams (0.7 lbs), making it lightweight and easy to handle.

The tool includes one removable black hinge pin to aid in the process of removing and reinstalling the original pin. It does not come with a set of replacement hinge pins.

Keep the tool clean and dry. Wipe it with a cloth after use and store it in a suitable place to prevent rust or damage.

Ensure you have adjusted the correct hinge knuckles. You may need to make further small adjustments or check if the issue is due to a worn hinge or frame rather than a bent knuckle.

Ensure the integrated hinge pin remover is properly seated. You may need to gently tap the bottom of the pin with a hammer while applying upward pressure with the tool. A drop of lubricant can also help.

Verify that you are using the tool with a standard residential hinge. The tool is designed to grip these common sizes; unusual hinge dimensions may not provide a secure fit.

Apply pressure slowly and incrementally. If a knuckle is severely damaged or broken, hinge replacement may be necessary. This tool is for correction, not for repairing severely damaged hardware.
