Thermal patio door handle & lock

Thanks for posting! Your handle set looks like it could be our 82-081 keyed mortise style handle set. Look over the dimensions and compare them to your handle to confirm that this is the right replacement. You'll especially want to confirm the distance between the installation holes.

Dimensions for 82-081

The internal mortise lock, which is sold separately, appears to be our 82-238. Again, compare the measurements to your existing mortise locks to confirm that is the mortise lock you'll need.
