The Design House Coventry 2-Way Latch Entry Handle Set accepts a key on one side of the lock but is operated by a turn-button handle on the other side. Designed for left or right-hand doors, 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 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. Designed and manufactured by Design House, the trusted source for quality lighting, hardware, plumbing, kitchen, and bath products for every taste and budget.
