Frequently Asked Questions
- What is the difference between a locker latch and a cam latch for marine use?
– Locker latches secure doors with a sliding or barrel mechanism, while cam latches use a rotating cam to clamp and hold, often offering locking options for security. - Why is 316 stainless steel preferred for marine latches?
– It provides superior corrosion resistance in saltwater environments, reducing rust and preserving strength over time. - Do these latches require special tools for installation?
– Most marine latches use common hardware and mounting patterns, but always verify hole spacing and screw compatibility with your door material. - Can anti-rattle features extend latch life?
– Yes. Anti-rattle designs reduce wear from constant vibration, improving smooth operation and longevity. - Are locking latches necessary for transom doors?
– If the door leads to the exterior or must stay closed in rough seas, a locking latch provides added security against movement. - What should I measure before buying a latch?
