Hi,

Sliders were installed in 1972 (brand unknown.) They work perfectly, have never leaked, the frame is larger than today's "standard" sizes, but the lock on the handle is broken.

Tried a "universal" handle - the affixing plate was too short. Tried a $50 handle that had the right size affixing plate, but didn't have the locking pin - even though the packaging showed it was enclosed.

Rather than incurring the cost to replace the doors plus labor, is there a locking handle that might fit?
