The Design House 741322 Cambridge 6-Way Latch Entry Door Knob is finished in satin nickel and designed for left or right hand doors. The flat ball handle fits comfortably in your hand and the satin nickel finish matches your homefoots decor. This knob fits the two most common backsets in the U.S. (2-3/4-inch and 2-3/8-inch). The 1/2-inch latch bolt is plated in nickel and does not budge once in place. With privacy in mind, this product accepts a key on one side of the lock but is operated by a turn-button knob on the other side. Entry knobs are often used on front doors and back doors. Use this knob on standard 1-3/8-inch and 1-3/4-inch thick doors. This product has a 1-inch by 2-1/4-inch radius corner face plate and 5-pin security. If you are preparing your door for installation, the cross bore should be 2-1/8-inches in diameter and the edge bore should be 1-inch in diameter. This product is ANSI Grade-3 certified, which means this knob is rated for residential security.
