Questions & AnswersAsk a Question
I have an older Genie garage door opener... has to be at least 20 years old as was present when I bought my home (built in 1973) in 1999. It is what I believe you call a screw drive model... I could get the exact model number from my files but don't have them available to me at this moment. Lately the screw drive has been separating where it connects to each other... think there are 3 to 4 sections. As the weight of the door transfers to the next section, it separates and slides away from the first section driven by the motor. In looking at this kit... "Extension Kit (to 8') for 3 Piece, Screw Drive C-Channel Rails"... I see what appears to be a little sleeve/tube and/or half sleeve/tube. I suspect their purpose is for the full "sleeve" to slide over the connecting point between the screw drive sections holding them together... the half "sleeve" to snap onto the shaft to hold the full "sleeve" in place over the connecting point. If so... where can I buy just these parts and are there any assembly instructions you can share that confirms/tells me exactly how to use both the full and the half "sleeve"? Thank you.
It sounds like you are missing the clip and collar that connect the screw drive ends. Click here- In this part, look at the photo, it shows how they connect. If so, you will need the clip part and collar. Part numbers, 19807A04.S and 19806A04.S.

Can I install more than one extension kit to an 8’ door to move power head back to where I want to mount it?
No, you can only add one extension kit.
Hi, I have a Series II screw drive opener. The screw-drive in the middle section snapped in half between the collars which connect it to the first & third sections. Is there a replacement available for the middle section? Would this be the same thing as an extension kit? Operator Model ISD 1000 Thank you
The extension kit would not be the same. We do not sell just sections of the screw drive. Please contact Genie customer service at 1-800-354-3643.
I have a 9 ft door. Can I use these extensions with the MachForce 2 HP opener? If not, what do I need?
No, you cannot use two extension kits. This will only work on up to an 8-foot high door with the added extension kit.
Can this be use on Excelerator ISD990?
No, this extension kit will not work with the ISD990 model garage door opener. We no longer have an extension kit for the ISD990.
