Questions & AnswersAsk a Question
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 at www.geniecompany.com.
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.
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.
My garage doors are exactly 7 feet 6 inches, do I need the 39026R Extension Kt for the Genie model #7155L-TKV opener?
Yes, you would need the extension kit for a 7' 6" garage door. he 7155L-TKV model garage door opener will work out of the box on a 7' high door (without the extension kit).
If you get the extension package it the belt a 8ft belt or do you have to buy it separately?
The extension kit comes with an 8-foot belt.
