Buying Guide
Key considerations when selecting marine-grade door hardware:
- Material and corrosion resistance: Look for 316 or 316L stainless steel for saltwater exposure and high humidity.
- Application type: Choose hasps for external doors and hatches, latches for anti-rattle needs, or mortise locks for security with keys.
- Mounting and hardware compatibility: Confirm dimensions, hole patterns, and whether your door supports turning padlocks or padlock eye mounts.
- Security level: If external doors require tamper resistance, prefer non-removable pins and lockable latches with robust padlock compatibility.
- Maintenance and finish: Smooth, burr-free surfaces reduce wear on seals and reduce snag risk during operation.
Comparison snapshot:
- Best for high corrosion resistance: Bonsicoky hasps and Milcraft hasps.
- Better for anti-rattle needs: ODYSUNRAL latches with center tensioning cam.
