Cylinnda 10-Pack 5/8" Cam Locks — Keyed-Alike Zinc Alloy Tubular Replacement for RV Toolboxes Mailboxes, Chrome, 2 Keys Each

Cylinnda 10-pack 5/8" tubular cam locks are a keyed-alike zinc-alloy replacement set designed to secure RV compartments, toolboxes, mailboxes and cabinets with durable, rust-resistant construction.

If you need a straightforward, reliable way to replace worn or common OEM locks on travel trailers, campers, boats or utility storage, this bundle delivers ten 5/8" cam locks plus two identical metal keys per lock so every lock in the set opens with the same key. Built from chrome-plated zinc alloy and engineered to fit standard 3/4" mounting holes, these cam locks offer a 90-degree turn action and multiple cam-arm options for flexible installation on thin doors and panels.

Will these cam locks fit my RV storage door or toolbox?

These locks are made to fit doors up to 3/8" (9.5 mm) thick and require a ≈3/4" (19 mm) mounting hole. Verify both your door thickness and the latching distance before ordering to ensure compatibility.

• For door thickness: less than 3/8" (9.5 mm).
• Mounting hole diameter: about 3/4" (19 mm).
• Max latching distance: 5/8" (16 mm) — measure from door face to latch point.
• Comes with straight and offset cam arms, adjustable for common installations.

How secure and weather-resistant are these replacement locks?

The bodies are cast from premium zinc alloy and finished in chrome plating to resist rust and outdoor exposure. Tubular cam technology reduces easy duplication of common flat keys, and the set’s upgraded components improve longevity versus basic OEM parts.

• Chrome-plated zinc alloy resists corrosion and outdoor wear.
• 90° rotation gives clear locked/unlocked positions; key removable when unlocked.
• Keyed-alike in each package for convenience and fewer keys to carry.
• Lifetime warranty and 30-day money-back guarantee for added assurance.

What do I get in the package and can I get different lengths keyed alike?

This listing includes ten 5/8" tubular cam locks and twenty identical metal keys (two per lock). If you need multiple lengths keyed alike, Cylinnda offers customization—contact customer support to request mixed-length sets that share the same key.

• 10 × 5/8" cam locks, chrome finish.
• 20 × matching metal keys; all locks in the order keyed alike.
• Straight cam arms in two usable lengths (2.00" and 1.65") and offset cam length 2.00".
• Support for 1-1/8" and 7/8" sizes available separately—check product images for size guidance.

How easy is installation and what tools are required?

Installation is straightforward: the lock slides into a 3/4" hole, secures with the included nut, and the cam arm is fitted to the hub. No specialty tools are required beyond basic hand tools; rotation is a simple 90° turn to lock or unlock.

• Slide lock into 3/4" mounting hole and tighten retaining nut.
• Attach cam arm and choose desired length or mounting hole for adjustment.
• Turn key 90° to operate; key is removable in unlocked position.
• Ideal for quick swaps on cabinets, drawers, toolboxes and RV compartments.

Who this is for: Cylinnda’s 10-pack 5/8" tubular cam locks suit RV and boat owners, mobile craftsmen, fleet managers and homeowners who need multiple matching locks for compartments, tool chests, mailboxes or cabinets. Choose this set if you want corrosion-resistant hardware, keyed-alike convenience, and a simple retrofit for standard 3/4" holes—especially useful when replacing common, easily duplicated OEM locks with a more robust alternative.
