HYWJC Paddle Latch Replacement for Toolboxes 5-1/2" x 4-1/4" — 304 Stainless Steel, Includes Keys & Gasket

HYWJC paddle latch is a 304 stainless-steel toolbox lock kit with two keys and a waterproof sponge gasket for quick, secure replacements.

This compact replacement latch measures 5-1/2" x 4-1/4" and is built for metal toolboxes, truck boxes, and storage chests where corrosion resistance and a tidy, flush appearance matter. Designed to swap out worn or broken paddle locks, the kit includes the latch body, a sponge gasket for moisture sealing, and two matching keys so you can get back to work without custom key cutting.

How durable is this latch in wet or salty conditions?

The latch body is formed from 304 stainless steel to resist rust and corrosion in humid or marine environments. The puck-style keyhole cover and included sponge gasket further reduce water intrusion at the mounting face.

• 304 stainless body resists oxidation and common corrosive agents.
• Keyhole automatically covers to block dust and splashes.
• Sponge gasket provides a basic waterproof seal at the mounting surface.

Will this fit my existing toolbox opening and how easy is installation?

With an overall face dimension of 5-1/2" x 4-1/4", this paddle latch fits many common replacement cutouts and can be mounted using standard screws after drilling mounting holes. Installation is straightforward for anyone with basic hand tools.

• Faceplate dimensions: 5.51" x 4.33" for common retrofit compatibility.
• Mounts with screws—no welding or complex fabrication required.
• Replace worn locks in minutes using a drill and screwdriver.

What comes in the package and how secure is the keyed lock?

The package contains one stainless-steel paddle latch, one sponge gasket for sealing, and two matching keys so you have a spare. The keyed mechanism provides basic theft deterrence suitable for tools and equipment storage but is not a high-security safe-grade lock.

• Included parts: latch, sponge gasket, two identical keys.
• Keyed cylinder offers convenient locking and unlocking on job sites.
• Ideal for securing tools and accessories rather than high-value vaults.

How does the latch handle daily wear and maintenance?

The paddle design minimizes snagging and the stainless surface wipes clean easily; occasional lubrication of the lock cylinder and checking the gasket for compression keeps the latch working smoothly. The keyhole cover helps reduce dirt buildup and extends service life.

• Paddle face stays flush to reduce accidental catches and abrasions.
• Wipe the stainless surface and apply light cylinder lubricant yearly.
• Replace the sponge gasket if it becomes compressed or damaged.

Who this is for: The HYWJC paddle latch kit is intended for tradespeople, fleet owners, and DIYers who need a straightforward, corrosion-resistant replacement for a toolbox or truck box paddle lock. It’s best when you want a durable, low-profile lock that’s easy to install and provides reliable day-to-day security for tools and gear rather than high-security protection.
