These roof lifts cable tie onto each side of the run lids either 30" across or 4ft. They spring up in the centre and create an effective rain dispersal. Supplied with cable ties for fixing.
Fix so that you can still hinge up your lid where you wish to, the roof lift won't affect this, you just need to unhook the cover first.
Recommendations:
- 8ft x 4ft run - 2 x 4ft roof lifts
- all other sizes - 1 roof lift
