Don't confuse these precious real crystal knobs for a hollow glass knob. They are very heavy, including solid heavy brass fittings, and include all hardware necessary for mounting. If you can find these rare beauties elsewhere, don't be surprised to see them priced well over $100 each, but they are very hard to find. The crystal part only measures 2 5/8" wide x 1 1/2" deep. The standard overall length of the entire unit is 7" and it is adjustable to fit thicker doors to 7 1/2".
