Sliding door locks are most commonly the steel mortise style. These types of locks typically have handles with mounting screws spaced 3-15/16" apart.
You can use different styles of handles, so long as the handle set uses that screw spacing.
That allows you to substitute a handle that might be easily avaialble in your local hardware store. If you cant find one locally, please let me know I may have some on hand
This handle has a white painted housing and a wood pull handle. The thumb lever for the mortise lock works with all types of steel mortise latches.
This handle set comes in 2 colors, all white or all black. The interior handle is not quite as high as the C1128 so it is less likely to get in the way of drapes or blinds.
