I am looking to replace a broken patio door handle. The broken part is the lower part shown in the photographs. The spigot that holds the screw in place has broken. It looks like your 82-080 mortice handle, however, the fasteners on my door handle are on the plate that the handle fastens too, not the RHS plate as shown in your picture of the 82-080.
Appreciate any help.
Regards
Martin
