Cylinnda 5/8" Cam Lock 10-Pack — Keyed Alike Toolbox & RV Mailbox Replacement, Zinc Alloy Chrome Weather-Resistant

This is a 10-pack of Cylinnda 5/8" tubular cam locks with chrome zinc-alloy bodies and 20 identical keys for replacing toolbox, RV, mailbox, drawer and cabinet locks.

If you need a reliable, weather-resistant replacement lock set for multiple compartments, this kit supplies ten durable cam locks that all use the same key. Each lock is made from zinc alloy with a chrome finish, opens with a 90° turn, and fits doors under 3/8" (9.5 mm) thick. The package includes two keys per lock for convenient spares and quick installation hardware for standard 3/4" (19 mm) mounting holes.

Will these locks fit my RV or toolbox doors?

Measure two things before buying: the door thickness and the latching distance (from the door face to where the cam must engage). These Cylinnda locks work for doors thinner than 3/8" (9.5 mm) and a maximum latching distance of 5/8" (16 mm). The mounting hole requirement is roughly 3/4" (19 mm).

• Door thickness: under 3/8" (9.5 mm)
• Mounting hole diameter: ~3/4" (19 mm)
• Max latching distance: 5/8" (16 mm)
• Offset cam length: 2" (50 mm); straight cams adjustable to 2 lengths

How secure and weatherproof are these replacement cam locks?

Constructed from premium zinc alloy with a chrome plating, the locks resist rust and are built for outdoor use on RVs, boats, and toolboxes. They use tubular key technology that’s more difficult to pick than basic flat-key cylinders. The set comes keyed alike so one key opens every lock in the package, reducing the number of keys you carry.

• Material: zinc alloy with chrome finish for rust resistance
• Tubular cam locking mechanism for improved security
• 90° rotation; key removable when unlocked
• All locks in the set are keyed alike (20 keys included)

What comes in the box and can I get different lengths keyed alike?

The kit contains ten 5/8" cam locks and twenty identical metal keys, allowing spare keys or distribution across users. Cylinnda also offers other cam lengths (7/8" and 1-1/8") — contact customer service if you need multiple lengths keyed alike or a custom configuration.

• Quantity: 10 locks, 20 identical keys
• Cam options: offset 2" (50 mm); straight cams adjustable to 50 mm or 42 mm
• Keying: keyed alike within the same order by default
• Support: lifetime warranty, 30-day returns, customer service available

Who is this for: This 10-pack is ideal for RV owners, boaters, handymen, fleet managers, contractors, and homeowners replacing multiple compartment locks at once. Choose this set when you want durable, weather-ready replacements that simplify access with a single key and include spare keys for convenience.
