Both worked fine when removed, just took them down to upgrade to smart openers. Good for my 7’ doors, would probably need a rail extension kit for an 8’. Includes wired opener and remotes, safety sensors, etc. Replace a broken opener, add power to a manual door, or find a creative and nefarious use for two large-ish screw drives. Asking $50 each OBO. Can deliver to the space, or feel free to give me a shout for pickup in Frisco/McKinney area.
