C3-1575 Sanitary Compression Lock
The sanitary compression latch is specifically designed for equipment in the food, beverage, pharmaceutical, biotechnology, and other high hygiene level industries. Unlike standard sanitary quarter-turn locks, this product continues to exert axial compression after the latch tongue rotates to the locked position, further drawing the equipment door panel towards the door frame, ensuring the sealing strip remains in a stable compressed state. This "rotation + compression" working method enables quick locking, door panel pre-tensioning, enhanced sealing, and vibration resistance, making it particularly suitable for sanitary equipment that requires frequent high-pressure cleaning, has sealing requirements, or experiences inherent vibrations.

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 OEM/ODM customization for secure corner locks?
Yes, we support customization of materials, structures, surface treatments, 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 restrictions.
What is the difference between a sanitary compression latch and a standard sanitary cam lock?
The standard sanitary rotary lock primarily completes a 90° rotation of the lock tongue. The compression lock also generates an axial tightening action after the lock tongue is in position, further pressing the door panel against the door frame, thereby enhancing sealing, vibration resistance, and anti-loosening capabilities.
What material is the blue sealing ring made of?
Made with blue TPU sealing material commonly used in food equipment. The blue design also facilitates quick identification of seals in food production environments. If direct food contact is involved, relevant food contact material compliance documents can be provided as per project requirements.
What does IP69K mean?
The P69K is primarily designed for high-pressure and high-temperature spray environments, making it suitable for equipment frequently cleaned with high-pressure water guns in food factories. Actual supply should be based on the corresponding IP test report and installation conditions.
Can it withstand high-pressure cleaning?
The sanitary compression lock can be designed with an IP69K structure for high-pressure and high-temperature washdown environments. However, IP69K must be verified through actual testing of the complete locking mechanism and cannot be inferred solely from materials or seals.
