This item changes the modern ugly round holes in doors so that antique hardware can be used.
This adapter plate will work with our L-6 tubular passage latch. It cannot work with other companies' latches that are more than 3/4" thick.
Door must be a minimum of 1 1/8" thick. Plastic sleeve slides over the latch body and is held in position by screwing metal halves together.
Once in place behind a 2 1/4" diameter (or larger) doorknob rosette or a door plate, the Fitting Kit is not visible.
