Question:
I have a ramp door that is 72 inches wide, the weight is approximately 160#. What is the minimum distance between the drums on your CB250D96SHD can they be adjusted to a narrower width?

Expert Reply:
The whole assembly (96 inches wide) would be too long to trim down and still fit. I'd recommend going with the slightly smaller # 362SA7, which can be trimmed down. The spring has a capacity of 150 lbs. That means you will need to slightly support the door but it will be very minimal and will allow great assistance with operation.
The # CB250D96SHD although rated for up to 250 lbs is also only able to be cut down to 80 inches.
We strongly recommend having a professional overhead door technician install the spring for you. The spring needs to be tensioned, and if it lets loose accidentally it would fling tools at high enough velocity to easily kill someone.
