The latches are made entirely of a self-extinguishing plastic material, classed as self-extinguishing under UL 94 V-0. The classification under UL 94 V-0 (Underwriters Laboratories) describes the fire behaviour of plastic. In the test, a plastic test specimen with a certain shape and with certain dimensions is placed vertically and set on fire. For classification V-0, the flame must go out within 10 seconds without generating burning drops. |
For installation, set a hole in the door, cover or hatch as shown in the outline drawing. The latch is inserted into the hole from the front and screwed on with the mounting nut from behind. Then the latch arm is fastened using the stainless steel screw. The required installation bore in the door leaf, is usually generated by punching or laser machining in series production. The installation bore diameter can also be created by drilling or milling as shown in the outline drawings. For small series and steel sheets below 2 mm thickness, the sheet metal punch GN 123 are the tool of choice . |
