5 Pack Tool Box Lock with Keys

Cylinnda 5-pack 5/8" tubular cam locks are a keyed-alike replacement set for RV compartments, toolboxes, mailboxes and cabinets that provides corrosion-resistant zinc-alloy security with two cam lengths and ten matching keys.

When you need dependable closure for RV storage doors, camper compartments, tool chests or small utility doors, these cam locks deliver a compact, weatherproof option engineered for easy installation and daily use. Each kit contains five locks and ten identical metal keys so you can operate every lock in the set with a single key, plus extras for spares. The chrome-plated zinc alloy construction resists rust and outdoor exposure while the tubular key mechanism offers better security than common flat-key replacements.

How do these locks install and fit my compartment door?

Installation is straightforward and designed for common RV and utility door setups: the lock body fits a standard 3/4" (≈19mm) mounting hole and secures with a threaded nut. The lock is intended for doors up to 3/8" (9.5mm) thick, and the cam engages with a 90° rotation for secure latching. Straight and offset cams are included to match different latch geometries.

• Mounting hole diameter: ≈3/4" (19mm)
• Suitable door thickness: less than 3/8" (9.5mm)
• Rotation: 90° with removable key in unlocked position
• Includes straight and offset cam arms for different latch alignments

What lengths and cam options are included and adjustable?

The set contains cams sized to work with typical RV and toolbox latch distances: a maximum latching reach of 5/8" (16mm) and offset cam length of 2" (50mm). The straight cam supports two usable lengths — 2" (50mm) and 1.65" (42mm) — plus the upgraded straight arm is slotted for three mounting positions, so you can fine-tune fit without cutting metal.

• Max latching distance: 5/8" (16mm)
• Offset cam: 2" (50mm)
• Straight cam usable at 2" and 1.65" lengths
• Adjustable holes on straight cam for flexible installation

Are these locks durable in outdoor or marine environments?

Yes — the bodies are cast from premium zinc alloy and finished in chrome to help resist corrosion and wear from weather exposure. The chrome plating provides water resistance and a smooth surface that reduces friction during repeated use. Tubular key construction is also less vulnerable to common flat-key picking attempts, improving day-to-day security for outdoor gear.

• Material: premium zinc alloy with chrome finish
• Rust- and water-resistant plating for outdoor use
• Tubular key design for enhanced everyday security
• Built for repeated open/close cycles on travel gear

What do I get in the package and how do keyed-alike sets work?

The package contains five 5/8" cam locks and ten identical metal keys, so any key in the set opens any lock included in the same order. If you purchase multiple sets of the same cam length together, they will come keyed alike by default; custom cross-length keying can be arranged by contacting the seller before purchase.

• 5 locks + 10 same-key metal keys per pack
• All locks in the same-order set are keyed alike
• Options available in 5/8", 7/8", 1-1/8" and two finish choices
• 30-day money-back, lifetime warranty and customer support
