Hormann Retractable Door Springs

[ernieh]

The springs on my Hormann Retractable door are at end of life and I need to replace them. These are the triple extension springs located at either side and are pre-loaded.

I'm wondering if anybody here has done that and if so how did you go about relieving the tension and resetting the tension on the replacements. Any help would be much appreciated.

I've searched YouTube but there doesn't seem to be any help for that particular type of spring; plenty of help for the other, overhead type and those with a screwed adjustment.

I got a local garage door man to replace them, cost me £80 but felt safer having watched a few clips and read a few horror stories.

+1 - not something I would tackle myself.
