The picture shows the inside portion of handle to a Pella fir, patio sliding door (clad on the outside). The outside portion got broken off and is lost. The handle is a single inside latch.....no key lock. The ID # is 22650 Ferndale. Other numbers are just patent #'s 5125703/D340.398. Dimensions are: Length 8 1/2", width 1" Distance between screw centers is 3 15/16". Material is brass. Door thickness is 1 7/8".

We have the 82-075, but it is meant for 1-5/8" thick doors, not 1-7/8". The key cylinder tail might not be long enough. If it's not, you can purchase an 82-310 key lock separately, cut it to the proper size, and then install it in the 82-075 handle set.
We also have non-keyed handle sets like our 82-041 or 82-079. You may find these to be a little more flexible, but they are not the same brass style as your original.
