Retrofittable mechanism for adjustment of roller door spring torsion
Disclosed herein is a retrofittable mechanism 10 comprising a roller door shaft support bracket 12 for fixed connection to a wall mounting bracket 300. The bracket 12 defines an opening 12a for receiving one end of roller door shaft 202 and, when the shaft 202 is engaged in the opening 12a, for restraining the shaft 202 against translation transverse to the shaft's axis but permitting rotation of the shaft about its axis. Collar 16 of mechanism 10 is fixedly connectable to shaft 202 and coupling 18 is defined between bracket 12 and collar 16. Coupling 18 is configured to selectively permit and prevent relative rotation between bracket 12 and collar 16 when mechanism 10 is installed in roller door assembly 100. tu CD, rr r4_ __ _ toN
