A-1531 Marine Compression Latch
This is a marine compression lock made of SUS316 material, featuring a low-profile embedded round structure. It is suitable for yachts, vessels, deck hatches, cabin storage doors, equipment access doors, RV compartment doors, and outdoor equipment boxes. The operation involves lifting the handle to release the compression, followed by rotating the lock tongue to open. After closing, the compression structure tightens the door panel against the gasket, reducing vibration loosening, door panel noise, and poor sealing. The rear locking distance is adjustable, accommodating different door thicknesses, frame positions, and gasket compression amounts.
- Material: SUS316

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 you.
Does ForndLock provide rotary locks for OEM/ODM customization?
Yes, we support customization of materials, structures, surface treatments, lock cylinder types, and markings for rotary locks to meet project requirements.
Where is this lock mainly used?
Mainly used for yachts, vessels, deck hatches, cabin storage doors, marine equipment access doors, RV compartment doors, outdoor equipment boxes, and vehicle storage compartment doors. This type of structure is very suitable if customers require low profile, corrosion resistance, and compression sealing.
What is the difference between it and a standard marine handle lock?
The standard pull handle lock is primarily responsible for opening doors or simple locking; this model is a lift-and-turn compression lock that tightens the door panel inward when closed, enhancing sealing while reducing vibrations, looseness, and noise.
Why Use SUS316 Material?
Marine vessels, yachts, and seaside equipment are often exposed to high humidity and salt mist environments. SUS316 is more suitable for corrosion-resistant applications than standard zinc alloy and SUS304, making it particularly ideal for marine hardware.
