Using a 1/2HP Door Opener for a 16' Wide Sliding Door
Hopefully this forum will help me with this issue...
I have a 139.53648SRT2 Model Craftsman Door Opener which I used several years for a 8' wide sliding door, actually I used two for two doors the same size at the same gate. Now, I remodeled my house and put a new single gate, 16' wide!, with double wheels and top and bottom.
Somebody told me I could use one of the same door openers to operate the sliding gate. I bought an extension T-rail/chain/cable for it and added the extra length needed. Another piece of info is it takes about 230 lbs to initially pull/push the gate to open or close (A dealer employee told me the capacity of these motors is about 340lbs...).
Well, I did all the required extension work and tested the motor before installing... only to find out it only slides about 11' and not the 16 feet I need to fully open or close my gate.
Any ideas about this situation? Am I using the right door opener or I have to find or buy another model? Any advise will be appreciated.
Thanks for any help... Blessings,
