Southco Flush Entry Door Latch with Key Lock
Features include key locking for access restriction and a natural aluminum finish. It is designed for doors with 12.7 mm (.50 inch) thickness. Best for boat or cabin doors where secure access is needed without visible hardware on exterior surfaces. This latch suits a standard flat or flush door profile on lightweight marine interiors.
Who it’s best for: boat owners or vessel interiors needing a discreet, secure locking latch. Why selected: combines a locking mechanism with a compact, flush design suitable for thinner doors. Caution: ensure the door thickness matches the 12.7 mm specification to avoid misfit or operation issues.
Perko Sliding Window Stop
Key utility is a chrome-plated zinc alloy sliding stop with a polymer cover on the stopping plate. Sold as a single unit, it provides a simple solution for restraining movement of sliding panels. Best for marine windows or small doors where a minimal stop is needed and corrosion resistance is a priority.
Who it’s best for: owners configuring sliding windows or light doors that require a compact stop. Why selected: straightforward, corrosion-resistant stop with protective polymer cover. Caution: designed as a stop, not a full latch; pairing with a separate latch may be necessary for complete security.

Buying Guide
- Material and corrosion resistance: Prioritize 316 stainless steel or aluminum for saltwater exposure and humidity.

- Two-way openings and safety: For pool areas or child safety, consider latches with dual-entry or safety features.
- Maintenance and durability: Look for smooth operation features like friction pads and anti-rattle design for long-term performance.
