  • The Genie 8’ door extension kit for model 7055 opener! What is the total length of this rail? From the front wall/door end of my garage to the center beam is exactly 11 feet so if I buy the model 7055 opener with the extension kit will it fit within that 11 feet? I have an old leer Genie, screw drive and it’s 18years old, the installer may have modified it to fit, in not sure! I installed a Genie 7055 two weeks ago on the other side but didn’t need it to open the 8 ft. door all the way but it’s very close! I need this side to open all the way! Hope you can help, talked to three techs at Genie and they didn’t know!

    The extension kit will add 12 inches to the total length of this garage door opener. For the model 7055, the normal total length is 116 inches total. With the extension kit, you would have 128 inches. Also- if you have the 7055 that has the battery back up attached, you would have to add 3 more inches (so total with the extension kit, and battery back up would be 131 inches). I hope this helps! If not, please let us know.

  • Is this what i need for a replacement rail for the genie 750 model for a 8ft door.

    This would only add the additional foot to a regular 7-foot rail. If you are trying to replace the entire rail, this would not be what you need. Please contact Genie customer service at 1-800-354-3643 for additional assistance.

  • my door is 9 feet. i want to buy the genie opener but genie does not make an extension kit to accommodate a door larger than 8 feet?

    We do not make an extension kit for a 9-foot high door. You would need to contact a Genie professional dealer for a rail to accommodate that. You can locate one near you by entering your zip code here.

  • Will this extension kit work on model 3142?

    No, you would need Extension Kit (to 8') for 3 Piece, Belt Drive C-Channel Rails for the 3142.

  • Will both models EKTB and EKTR work for an Genie Model 7055 purchased from Lowes? Genie 1.25-HP Belt Drive Garage Door Opener Battery Back-up. Lowes is showing Item #2514190 Model #38959Y

    Yes, these are both belt drive extension kits for the 7055 garage door opener.

  • Do you make an extension kit for a 10' door from my 7 Door. I just purchased an extension kit Four and eight foot door. I need one for a ten foot door..

    For any door over 8ft tall you must go through a local dealer for a one-piece rail. If you do not know who your local dealer is you can locate one here
