These Naissian locks are designed for a ¾” (0.75″) hole diameter and fit most RV storage doors, trailers, and cabinet openings with a double D-hole configuration. The package includes two locks with four keys per set, and keys are aliked within the set for easier access.

Features include a simple 90-degree turn to lock, with the key removable in the unlocked position. The kit is promoted for use beyond RVs, including tool boxes, cabinets, and drawers, making it versatile for boat interiors and deck storage. For mariners, this offers a dependable, low-profile locking solution that resists corrosion when paired with proper mounting practices. Always verify size guidance to avoid mismatches with your boat’s door panels.
WOOCH 5/8″ Thumb Operated Offset Cam Lock — 2 Pack
The WOOCH set prioritizes ease of use with a thumb-operated offset cam design. Constructed from zinc alloy die-cast housing, these locks aim for durability in marine environments and general RV applications, including boat compartments, storage doors, and tool boxes. The non-locking thumb turn provides a simple locking action for quick access, and the rugged housing is intended to withstand outdoor exposure. They’re positioned as a convenient option when you need a quick, repeated locking solution for multiple compartments.
For boat use, consider their suitability where non-key access is acceptable or where a quick-release access point is desired. As with any marine hardware, ensure proper sealing and mounting to resist salt spray and humidity. This pair is useful to outfit several compartments with a cohesive locking style while keeping installation straightforward.
Cylinnda 10 Pack Cabinet Lock 7/8″ — Keyed Alike
These Cylinnda locks are designed for standard 3/4 inch mounting holes and are sold as a 10-pack with keyed-alike capability. The zinc alloy body offers durability, while black plating provides corrosion resistance in outdoor environments. The product notes emphasize a quick 90-degree opening, easy installation, and a single keying system that simplifies key management across multiple compartments on a boat or RV. They’re suitable for cabinet doors, tool boxes, and storage compartments that require reliable locking with a consistent key set.
Key considerations for boats include verifying the latching distance and door thickness to ensure a proper fit. The set’s large quantity supports upgrading multiple compartments at once, reducing the need to juggle different keys while keeping valuables secure from theft and humidity damage.
LATCH.IT 5/8” RV Storage Locks — 2-Pack
LATCH.IT offers a two-pack of 5/8” RV storage locks with a tubular cam design and four keys in the package. The design emphasizes metal construction and waterproofing features, with an included O-ring to help seal against moisture. The locks are described as 100% metal, which can provide better durability in damp marine environments compared to some plastic- or composite-bodied options. The kit is pitched as multipurpose and suitable for RV compartments, tool boxes, cabinets, and drawers, including boat storage applications where secure access is essential.
As with any marine hardware, consider how well the lock’s materials will hold up against salt exposure and humidity. The presence of a waterproofing O-ring is a plus for boats, but ensure proper mounting and periodic maintenance to prevent corrosion over time. The four-key set allows sharing access with trusted crew or family while maintaining security for valuables aboard a vessel.
PTEROMY 5 Pack Cabinet Lock 5/8″ — 5 Locks
PTEROMY presents a 5-pack of 5/8″ tubular cam locks with a complete kit that includes four tubular lock keys, mounting hardware, and a choice of chrome or black surface finishes. The locks are designed for RV compartments, cabinets, drawers, and other storage doors, with waterproofing considerations noted. The kit emphasizes a complete set with multiple keys and plates, facilitating installation across several compartments or applications on a boat. The metal construction supports durability in outdoor environments, and the product notes highlight compatibility with a variety of installations, including tool boxes and storage chests.
For marine installations, assess the fit against door thickness and mounting hole diameter. The availability of spare keys and a straightforward 90° turn opening makes these locks practical for boat interiors where reliable access is needed without complex electronics or batteries. As always, ensure appropriate seals and maintenance to maximize longevity in saltwater conditions.
Buying Guide
Purchase considerations for boat storage locks include fit, durability, and keying options. Keyed-alike sets simplify access for crew and family, but verify that all locks in a package use the same key code to avoid mismatches. Check lock diameter and mounting hole requirements (commonly 3/4 inch) and confirm door thickness compatibility to prevent binding or misalignment. Material quality matters in marine environments; look for zinc alloy or other corrosion-resistant metals and, if possible, waterproofing features or O-rings to help resist moisture ingress.
Lock type matters as well. Tubular cam locks provide resistance to picking and offer straightforward operation with a 90-degree turn. Thumb-turn locks or non-keyed variants can be convenient where quick access is needed but may be less secure. For boats, consider locks with sealed housings and robust sealing to withstand humidity and spray. If you manage multiple compartments, choose a kit that offers spare keys or keyed-alike options to prevent key losses and simplify maintenance.
Application versatility is a plus. Locks sold in packs for RVs often translate well to boat compartments, cabinet doors, tool boxes, and drawers. Always verify measurements against your specific boat layout, including door thickness, latch distance, and mounting hole size. Finally, consider installation ease—some kits include multiple plates or adjustable arms to fit a range of depths and mounting configurations, reducing the need for custom fabrication.
