We recommend using a 3", 4" or 5" latch/lock.The strength of the spring found in a heavy-duty lock/latch will ensure the knob returns to it's original position.Supplied with matching SS wood screws.Our Polished Brass products are made from solid, unlacquered brass and have soft, golden hues which offer a depth of reflection. This works wonderfully in period dwellings but can also be used to bring a classic twist to contemporary properties. If left untouched, this finish will oxidise over time and naturally age to create a historically beautiful look. To restore these products to their former glory, simply polish using a dry cloth and some Brasso. Knob Size: 63mm dia. Projection: 60mm Rose Size: 63mm dia. x 10mm Spindle Size: 8mm (Threaded)
