5 Pack Tool Box Lock with Keys

These Cylinnda cam locks are replacement-ready hardware designed to secure exterior and interior storage doors on RVs, trailers, campers, boats and utility boxes. Built from zinc alloy with a matte black finish, each lock turns 90 degrees and accepts a tubular key; the package ships with ten identical keys so every lock in the set opens with the same key. The kit includes both straight and offset cam arms and supports common door thicknesses and mounting hole sizes for fast DIY swaps.

How do I know this lock will fit my RV compartment or toolbox?

Measure two dimensions before ordering: the door thickness and the latching distance (from the door face to where the cam must catch). The Cylinnda 5/8" cam lock fits doors up to 3/8" (9.5 mm) thick and a maximum latching reach of 5/8" (16 mm), and it requires about a 3/4" (19 mm) mounting hole.

• Door thickness supported: less than 3/8" (9.5 mm).
• Mounting hole diameter: approximately 3/4" (19 mm).
• Max latching distance: 5/8" (16 mm); offset cam length 2" (50 mm).
• Straight cam adjusts to 2" (50 mm) or 1.65" (42 mm) for fit flexibility.

What components and keys are included in the package?

The set contains five 5/8" tubular cam locks finished in matte black and ten identical tubular keys so every lock is keyed alike. You’ll also find cam arms that accommodate straight or offset applications and mounting hardware suitable for common compartment installations.

• Five keyed-alike tubular cam locks, matte black zinc alloy.
• Ten matching tubular metal keys — two spares per lock.
• Straight and offset cam arms, adjustable mounting holes on straight cam.
• Quick-turn 90° action; key removable in unlocked position for safety.

How durable and weather-resistant are these locks for outdoor use?

Cylinnda cam locks are die-cast from premium zinc alloy and coated with black plating to resist corrosion and the elements. The materials and finish are chosen for outdoor storage doors, so they hold up to normal exposure on RVs, boats and utility boxes when installed and maintained properly.

• Premium zinc-alloy body for strength and long service life.
• Matte black plating for rust resistance and improved weather durability.
• Tubular-lock mechanism designed for reliable repeated use.
• Recommended for exterior compartments, toolboxes and cabinets.

Who is this for: The Cylinnda 5-pack 5/8" cam lock set is tailored for RV owners, camper and boat enthusiasts, handypersons replacing worn OEM CH751-style locks, and anyone who needs keyed-alike security across multiple storage doors. It’s a practical choice for DIY installers who want consistent keys for several compartments, spare keys on hand, and the option to switch between straight and offset cam configurations. If your application requires different dimensions, Cylinnda also offers other diameters and finishes — confirm measurements before purchase to ensure compatibility.
