Sliding glass door-

Hello,

Take a look at our 82-218 mortise lock and the related keepers to determine which would fit best in your door jamb. 

It also sounds like you may need new rollers if your door is difficult to move, though you should also check the track to make sure there is no damage or debris. We'd need to see photos of your roller removed from the door, along with dimensions, to identify a replacement. Thank you!

Hello,

Take a look and compare the specifications of the 82-020 handle set with 3-15/16" hole spacing to yours. If you're looking for a more modern option, you could also consider the 82-030. Thanks for posting.
