Finished in polished brass and designed for left or right hand doors, this knob and deadbolt fit 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. 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.
