CarriageDoorOpeners.com's handcrafted custom aluminum frames for wood carriage door designs feature exceptional longevity. We have created two different custom aluminum frames that are designed for the DIY home owner: one with a straight top, and one with an arched top. We use 6061-T6 lightweight aluminum alloy that will not warp, bend, or rust. Our frames include strap style hinges that come standard at a length of 14", made from powder coated iron. The installation of our carriage door frames are designed to make your finished carriage doors sag free, easy to automate, and make it simple to replace an existing opening or match a desired look.
