The basic composition is: shell, main part, lining plate, door buckle, plastic box and screw fittings. , The single tongue generally has only one oblique tongue, and there are two specifications of 50 and 1500px. This size refers to the distance from the middle hole of the plate lining to the square hole of the lock body.
