Note: For garage doors BGR with the use of SW 7012 reel and PA 77 and PER 77 profiles, it is mandatory to use asymmetric rings PWA 70 with WA 70 retainer springs or security springs WB. Therefore, configurations SW 7012 + PZ/78 and SW 7012 + PW/70 for profile PA 77 no longer apply.


Place the screw included in the set and the control plate in the ring PWA 70 [1] and then screw together. In the next step stick the self-adhesive pad on the ring [2]. Make incision in the pad to create the hole for the Allen key [3] in the place of existing hole.
