C1-1631 Compression Lock
The ForndLock M16 Adjustable Compression Latch is a compact industrial locking solution designed for equipment doors, access doors, and cabinet doors that require panel pre-tensioning, vibration resistance, anti-loosening, and sealed compression. Unlike standard quarter-turn locks, this product continues to generate axial tension after the latch rotates into the door frame, keeping the panel pressed towards the frame. By applying stable compressive force to the sealing strip, it reduces panel loosening, vibration, and noise during equipment operation, while also enhancing the sealing performance of cabinet doors. The product features an M16 mounting structure with a compact overall size, suitable for small equipment doors with limited installation space. The rear locking structure supports spacing adjustments to accommodate different panel thicknesses, frame positions, and sealing strip compression requirements. **Key Features** - **Adjustable Tension Structure** The locking spacing can be adjusted according to the actual panel structure, helping to compensate for panel thickness, frame position, and assembly tolerances, achieving a more stable locking effect. - **Compression Locking** During closure, not only does the latch rotate, but it also applies axial tension to the panel, maintaining continuous pre-tension on the panel and sealing strip. - **Vibration and Anti-Loosening** Especially suitable for engine equipment, air compressors, generator sets, construction machinery, and other continuous vibration conditions, effectively reducing panel loosening and operational noise. - **Compact M16 Structure** The miniaturized design occupies less space, making it ideal for compact control cabinets, equipment enclosures, and small access doors.

FAQ
Can you send samples?
Yes, we can provide a few free samples for the customer, but we hope that the shipping cost can be covered by your side.
Does ForndLock offer custom OEM/ODM safety corner locks?
Yes, we support customization of materials, structure, surface treatment, lock cylinder types, and markings for safety right angle locks to meet project requirements.
What is the minimum order quantity?
The general minimum order quantity is 200 PCS, but if stock is sufficient, flexible supply can be provided according to actual demand, with no minimum order quantity restriction.
Can this lock enhance the waterproof performance of the cabinet door?
One of its important functions is to compress the door seal, thereby helping to improve the sealing effect. However, the final IP rating depends on the sealing of the lock body, the installation of the sealing ring, the structure of the door panel, and the overall cabinet design, which needs to be confirmed through actual IP testing.
Why are there so many drive methods such as hexagon socket, tubular key, and handle?
They correspond to different access requirements. The hexagon socket tool-driven versions are suitable for equipment that only maintenance personnel can access; the tubular key versions provide stricter access control; the handle versions are suitable for doors that need to be opened frequently and do not require tool management.
Is this lock suitable for high-vibration equipment?
Suitable. The compression structure can maintain the pre-tension of the door panel, which is particularly valuable for vibrating equipment such as engineering machinery, generators, pump units, air compressors, and rail vehicles, while also reducing door panel collisions and abnormal noises.
