EarthCam sliding door handle and mortise lock
See attached.
It's tough to say what your mortise lock is without seeing it out of the door, but our 82-218 is similar in design. Look it over and let me know what you think.
As for the handle set, can you show me some more pictures of the two halves? Your photos show the underside, but I'd also like to see them from the front, as well. This is in regards to both the inside and outside handle. I'd also like you to confirm the installation hole spacing, center-to-center. It looks to be over 5" but I cannot tell the exact center-to-center dimension.
Thank you! While grabbing these photos for you, I noticed you had an older thread just a few weeks ago looking for the same thing. It appears Dave answered you here with a recommendation for this handle. Have you seen that yet? He said that yours isn't made anymore, but you may be able to get something like our 82-033 to work if you drilled new holes. I'm afraid we have no other solution for this old hardware.
