No hard to reach locations for screws. (certain cabinet designs require one screw)No Need to Remove Drawers: Unlike traditional latches that require you to remove drawers from cabinets to drill and screw in the latch. Qdos latches install with adhesive.Qdos Perfect-Installation Tool: Lining up the catch and the arm is tricky business. The Qdos Perfect-Installation Tool takes all the guess work out of the installation. Get it right the first time.Qdos SecureHold Adhesive: Offers a high-performance and durable bond specifically designed to secure Qdos products and can be removed without damage.One size doesn't fit all: As standard countertops have an overhang of 1.5” (38 mm) it’s necessary to have a longer arm for the top drawers. Qdos' longer Top Drawer SecureCatch Latches offer room to operate the latch, but keep the opening small enough to protect children. Lower drawers (that don’t have a counter overhang) need a shorter arm to create the same safe opening.
