Unknown Door Handle

Hello,

Your photos resemble the 82-087 handle set and 82-218 mortise lock. Take a look and compare the specifications on our product pages to yours. 

One strange thing is that the cut-out for your mortise lock does not appear to have any installation holes. Could you confirm how the mortise was held in the door before you removed it? Thank you. 

Your handle set looks like the 82-087 with an external key lock. We also carry the 82-089 non-keyed handle set but it is not available in the same metallic finish. 

As for the internal mortise lock, take a look at the 82-244 and see if the dimensions shown below will fit your door's specifications. 

Dimensions for 82-244

I'm not exactly sure what type of mortise lock you originally had in your patio door since there are no installation holes to accommodate the 82-218 mortise shown in your last photo. I'm going by the shape of the oval cut-out at the edge of your door. The 82-244 mortise lock has the same oval shape. You'll need to determine if the door cut-out has the same 7/8" width and 4-9/16" height. There should be mounting holes already inside the cut-out in the door to secure the 82-244. Take a look at the video on how to install the 82-218 mortise latch. The installation is similar to the 82-244.
