Solid bronze tubular deadbolt for the Ashley Norton Rectangular look, 3" x 2 1/2". For 1 3/4" doors (up to 3" single keyed or patio, 2 1/4" double keyed); 2 3/8" or 2 3/4" backset. A collar is needed on 1 3/8" doors or with a level bolt (sold separately).
Cast from art grade silicon bronze (White Bronze from a manganese-nickel bronze alloy) and hand finished; patinas are waxed and will develop a natural, lived-in contrast with use. Dark Bronze is the most consistent and most often stocked.
