Installation instructions can be found here

These insulated hinged garage doors have all the difficult parts pre assembled already and you have delivered a complete doorset.
You simply have to offer the doors in their prefitted frame into the opening and secure the fixing frame and then adjust levels in the process.

A level floor is essential for the best results and a square aperture also makes installation easier but there are adjustments all round and in all directions.
