Cylinnda 5-Pack 5/8" Tubular Cam Locks — Chrome Zinc Alloy Toolbox & RV Door Replacement, Keyed-Alike with 10 Keys

These cam locks give you a simple, uniform security solution when you need multiple locking points opened with a single key. Built from chrome-plated zinc alloy and sized for common RV and utility applications, the set includes five locks, ten matching metal keys, and adjustable cam arms so you can swap or upgrade existing compartments quickly. Each lock operates with a 90° turn and is removable in the unlocked position for convenience.

What parts come in the boxed set and how are the keys arranged?

The package contains five complete 5/8" tubular cam locks plus ten identical keys so every lock in this set uses the same key. If you order more than one set of the same length in a single purchase, all locks will share one key code by default.

• Five chrome zinc alloy lock bodies sized for 5/8" latching distance.
• Ten identical metal keys — two spares per lock included.
• Straight cam arms in two usable lengths (50mm and 42mm) and an adjustable straight arm with three mounting holes.

Will these locks fit my RV or toolbox door?

They are made to fit doors up to 3/8" (9.5mm) thick and require a mounting hole about 3/4" (19mm) in diameter. Measure your existing latching distance from the door face to the latch engagement point and match it to the lock’s 5/8" maximum latching distance.

• For door thickness: less than 3/8" (9.5mm).
• Mounting hole needed: approximately 3/4" (19mm) diameter.
• Max latching distance: 5/8" (16mm); cam offset: 50mm.

How durable are these locks for outdoor and marine use?

Cylinnda cam locks use chrome-plated zinc alloy which offers corrosion resistance for exterior exposures. The finish helps resist rust and the tubular mechanism is designed for repeated daily use in travel and storage environments.

• Chrome plating provides rust and water resistance for outdoor use.
• Zinc alloy body balances strength and weight for long service life.
• 90° rotation operation reduces wear on the key and mechanism.

Can I customize keying or get different lengths if needed?

All locks in the same-length order are shipped keyed alike so a single key opens every lock in that purchase. If you need different lengths keyed alike or a mix of finishes, contact customer support for a custom order option.

• Standard option: same-key for all locks in one-length orders.
• Custom orders available for mixed lengths keyed alike — contact seller.
• Available sizes: 5/8", 7/8", 1-1/8" and finishes include chrome and black.

Who is this for? If you maintain an RV, camper, trailer, boat, toolbox or any exterior cabinet and want an affordable, uniform replacement key solution, this Cylinnda 5-pack is aimed at DIYers, fleet owners and weekend travelers. It’s practical for anyone replacing worn tubular cam locks or consolidating multiple compartment keys into one reliable set. The included spares, adjustable cams and corrosion-resistant finish make it a convenient option for routine maintenance and upgrades without specialized tools.
