Southco Entry Door Lockset ProFlush

The Southco Entry Door Lockset ProFlush is a marine-grade locking mechanism engineered for vessels where corrosion resistance and reliable security are non-negotiable. This entry door lockset combines sealed construction to prevent water intrusion with dual lock-plug options, delivering the security and durability that offshore and coastal boaters demand from cabin hardware.

The ProFlush lockset is available in two security configurations. The star lock system employs a pin tumbler design for maximum security, while the 3-wafer flat key option provides accessible security with a stainless steel plug and reversible key functionality. Both configurations are sealed against salt spray and moisture—critical for vessels operating in marine environments where metal degradation occurs rapidly. The lockset accommodates both oval and square door frame variants, ensuring compatibility across different boat cabin layouts and retrofit applications.

This hardware suits weekend fishermen securing tackle storage and serious offshore anglers protecting navigation equipment and personal gear in cabin spaces. Boat owners managing multiple locks appreciate the reversible key option, which simplifies spare key management aboard. The sealed design eliminates the routine maintenance corrosion-prone locksets require in salt air, reducing replacement frequency over years of seasonal or full-time use.

Southco's entry door lockset addresses a specific challenge in marine hardware: balancing access convenience with corrosion resistance. Unlike stainless steel locks that still require periodic maintenance in harsh salt environments, the ProFlush design prioritizes sealed protection, making it a practical choice for serious vessel owners who prioritize durability over the life of their boat.
