Buying Guide
What to consider when choosing a boat sliding door latch
- Material and environment: For saltwater use, 316 stainless steel provides the strongest corrosion resistance. Aluminum is lighter and suitable for non-load bearing doors.
- Door thickness and fit: Confirm the maximum panel thickness and mounting dimensions before purchase to ensure proper fit.
- Operation and maintenance: Latches with anti-rattle features or friction pads reduce noise and wear in rough seas. Consider maintenance needs and ease of lubrication.
- Security vs. convenience: Stainless steel bolt latches offer strong security; nylon latches reduce weight and corrosion risk but may have lower load capacity.
- Appearance and finish: A polished finish looks nice on premium installations; ensure compatibility with your door design and hardware.
