Inspection door lock that does not compromise the design of the door for steel fixtures.

Clearance lock L-587 with nothing attached to the surface of the door! Pursuing the "ultimate simplicity."

There is a growing demand for the intention to "hide as much as possible" when it comes to hardware such as flat handles and hinges, as people do not want them to be visually prominent. In recent years, in tower-type condominiums, hotels, hospitals, and public facilities, there has been an increasing trend to emphasize design, such as using colored steel plates or stone cladding for corridor inspection openings. The "Clearance Lock" is a product that pursues "ultimate simplicity" to meet such needs. Since it is installed embedded in the frame, the only visible part from the front of the door is the handle insertion hole. It is unlocked using a dedicated handle (sold separately). When unlocking, simply rotating the handle causes the door to automatically open partially, eliminating the need for a knob. 【Features】 ■ No handle!? A simple design with nothing attached to the door surface ■ Locking is completed just by closing the door, with a one-action lock function ■ Can be installed on flush doors, meeting doors, and standard doors
