The perfect enhancement for traditional or contemporary homes, the Polo passage ball knob from Kwikset is made from one piece of brass. The rounded design is proportioned to comfortably fit the palm of the hand. A silver metal color with brushed accents provides a crisp, clean look to this polished brass finish. The knob top turns smoothly for easy opening. The knob rose"s smooth edge softens up the look for an aged appearance. A narrow shank sets off the perfectly spherical knob. This passage knob is adjustable for 2-3/8- to 2-3/4-inch backsets. The Kwikset 6-way adjustable latch that comes with this knob fits square-corner, round-corner or drive-in applications, and the latch has a 1/2-inch throw so that the door stays closed. Installation on standard doors is easy with this unit; a Phillips screwdriver is all you need. The purchase is backed by a lifetime mechanical and 5-year finish warranty, ensuring lasting function and exceptional beauty. --Brian D. Olson
