Made to use when a door knob rose is used with our glass door knob. Very few genuine antique glass keyholes have survived the years. Beautiful on antique furniture and cabinetry, too.
Please be extremely careful when tightening the screws to mount. Too tight, or a slip with the screwdriver will crack the glass. While you must be very careful when installing it, the results are lovely to behold.
Overall 2" high x 1 1/4" wide. Inside measurement of the keyhole: 3/4" high. Top of keyhole width is 1/4"; bottom width is 1/4". Narrows to 1/8" at neck. Screw holes at 1 3/8" cc.
