Garage Door Hardware Kits Calculator

Note: This form is only for standard lift doors that roll overhead and back into the garage. The information you provide can help with doors that have other types of lifts, but the tracks and torsion assemblies will need to be calculated separately. Helpful information is available on our How Vertical-Lift and High-Lift Garage Doors Work page.

Please bear in mind that custom kits can be more expensive because we specify hardware that exceeds industry standards. You've probably heard stories of doors that fall apart after a few years. As a rough rule of thumb, you can count on paying $6.00 per pound of door weight plus an estimated $500 for shipping. For example, the hardware for a heavy 350 pound double wide wooden door could easily cost $2100 plus $500 for shipping, or a total of $2600.

Because of the extensive time and expertise required to process hardware kits, we require a $100 deposit to provide a quote for a hardware kit. This fee will be deducted from the final order amount.
