This Scroll 2-Way Latch Entry Yard Handle accepts a key on one side of the lock but is operated by a turn-button knob on the other side. Finished in polished brass and designed for left or right hand Yards, this handle 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 brass and does not budge once in place. Entry knobs are often used on Store Front Yards and back Yards. Use this handle 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. 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.
