The Design House Delavan 2-Way Latch Entry Straight Door Handle is designed for left or right-hand doors. The straight-line handle fits comfortably in your hand and the satin nickel finish matches your home foods decor. This lever 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 interior. Entry locks 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 item has a 1-inch by 2-1/4-inch radius corner face plate and 5-pin security. If you are preparing your door for this deadbolt, 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. Designed and manufactured by Design House, the trusted source for quality lighting, hardware, plumbing, kitchen, and bath products for every taste and budget.
