[PREMIUM QUALITY HARDWARE] TICONN heavy-duty door handle is made of premium quality zinc alloy and brass parts to guarantee rust-free in a high humidity environment. The door lever has a thick and smooth coating that will not crack or face under direct sunlight for long-lasting product life. [REVERSIBLE AND FLEXIBLE] No need for any guesswork. All our TICONN door handles are reversible and can be installed left-handed or right-handed. The door latch can be adjusted to 2 3/8" (60mm) or 2 3/4" (70mm) from the edge. All our door handles work for doors with thickness ranging from 1 3/8'' (35mm) to 1 3/4" (45mm). [STYLISH SMOOTH SECURE] The same keys are shared between the keyed door handle and the deadbolt in each pack. But keys are not interchangeable between different packs for added security. [WIDE APPLICATIONS] The clean yet bold square shape door lever will give your door an elegant final touch. Multiple finishes are offered to work with all different color doors and lighting conditions. [TICONN BRAND QUALITY COMMITMENT] We stand behind the quality of our products.
