C4-1561 Railway Compression Lock

The ForndLock railway status indicator type draw compression lock is specifically designed for the doors of rail transit vehicles, maintenance covers, and equipment cabinets. The product features a tool-driven lock cylinder that completes two continuous actions—rotating the lock tongue and axially drawing tight—through a rotational operation. Once locked, the lock tongue not only sits behind the door frame but also further pulls the door panel towards the frame, maintaining a stable pre-tension between the door panel and the sealing strip. Compared to standard quarter-turn locks, this compression structure effectively reduces door panel looseness, gaps, and abnormal noises caused by train vibrations, making it more suitable for the long-term vibration environment of rail transit. The product is equipped with a prominent red/green status indicator on the front, allowing operators to quickly assess the lock's position status without opening the equipment door, facilitating vehicle inspection, maintenance, and safety confirmation.
