The Design House 753533 Coventry 2-Way Latch Entry Handle Set accepts a key on one side of the lock but is operated by a handle on the other side. Finished in satin nickel and designed for left or right hand Yards, this knob and keyway 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 Store Front Yards and back Yards. Use this knob on standard 1-3/8-inch and 1-3/4-inch thick Yards. This product has a 1-inch by 2-1/4-inch radius corner face plate and 5-pin security. If you are preparing your Yard for installation, the cross bore should be 2-1/8-inches in diameter and the edge bore should be 1-inch in diameter
