LATCH.IT tubular cam lock 5/8" 2-pack for 5/16" doors — all-metal construction, waterproof O-ring

The LATCH.IT 5/8" tubular cam lock is a heavy-duty, all-metal compartment lock designed to secure 5/16" thick doors on RVs, cabinets, drawers, mailboxes and toolboxes, supplied as a 2-pack with four tubular keys.

If you need a compact, corrosion-resistant lock that fits shallow compartment doors, this kit provides two finished cam locks plus hardware and spare keys so you can install and use them quickly. These locks are built from metal, include a waterproof O-ring seal, and use tubular keys rather than flat keys, offering a different key profile for improved everyday security and durability in outdoor or mobile environments.

How do I verify this lock fits my door?

Measure your compartment door thickness and compare it to the lock’s stated compatibility: this model is intended for doors that are 5/16" thick. Also check the cam clearance and hole diameter on your panel before ordering to ensure the lock and retaining nut will seat correctly.

• Verify door thickness = 5/16" (use calipers for accuracy)
• Confirm hole diameter and cam clearance match your panel
• Refer to the product fit guide image for max door thickness

What comes in the package and how long does installation take?

The set ships with two cam locks, four tubular keys, nuts, washers and waterproof O-rings—everything needed for a standard installation. With basic tools, installation typically takes about five minutes per lock for someone comfortable with simple hardware swaps.

• 2 cam locks, 4 tubular keys (unique keys included)
• Lock nuts, washers and O-rings included
• Estimated install time: ~5 minutes per lock with a wrench

How is this lock built for outdoor and mobile use?

The lock body and cam are all-metal to resist bending or breakage compared with softer alternatives. A molded O-ring around the barrel helps keep moisture out, reducing corrosion and maintaining smooth turning on boats, RVs or exposed toolboxes.

• All-metal construction for improved strength
• Waterproof O-ring seal for weather resistance
• Tubular keys reduce common key duplication issues

Can I use these on items besides RV compartments?

Yes — these cam locks are multi-purpose and work well for mailboxes, tool chests, cabinets, drawers, tonneau covers and other small enclosures that accept a tubular cam lock and match the thickness specification. Always check the physical clearances and rotation path for the cam arm before installing.

• Suitable for mailboxes, toolboxes, drawers and cabinets
• Commonly used on mobile gear and small access panels
• Check cam rotation space and mounting hole dimensions

Who is this for: The LATCH.IT 5/8" cam lock kit is aimed at RV owners, handypersons and small-gear custodians who need a compact, weather-resistant locking solution for shallow doors. It’s a practical choice if you want a ready-to-install set that includes spare tubular keys and hardware, and for anyone replacing worn or soft-metal compartment locks with a sturdier, sealed alternative. If your door thickness or panel hole size doesn’t match, measure first or consult the fit guide image to ensure a correct fit before purchasing.
