KLEIN TOOLS MODbox Caster Dolly 54828MB — Interlocking Mobile Base with Locking Casters, 250 lb Capacity

The Klein Tools 54828MB MODbox Caster Dolly converts any MODbox with cleats into a lockable, interlocking mobile platform designed for on-site transport and stable workstation setups.

Compact and built for professional jobsite use, this caster dolly snaps to compatible MODboxes to create customized rolling bases that move tools, materials, and supplies with less strain. Durable construction, a friction brake pedal, and front locking casters give crews the choice of a mobile cart or a secure stationary platform. Multiple dollies can latch together to expand capacity and footprint when needed, making the system adaptable to different tasks and loads.

How does the dolly attach to MODboxes and stay secure?

The dolly connects directly to MODboxes that have cleats, aligning to the box base and locking into place so the box becomes a mobile unit. A friction-based brake pedal stabilizes the assembly while you mount or arrange contents, reducing movement during loading.

• Direct cleat-to-dolly engagement for a simple snap-on fit
• Brake pedal locks the dolly during box placement and handling
• Two front locking casters prevent rolling when set as a workstation

Can multiple dollies be combined for bigger loads?

Yes — the 54828MB features side and rear latches so up to four dollies can interlock, creating a broader, more stable platform to carry larger or irregular loads. Interlocked units share a continuous base that spreads weight and increases handling versatility.

• Side and back latches allow seamless linking of units
• Interlocked platforms distribute weight across connected dollies
• Dual-wheel positions enable either closer connections or standalone stability

What mobility and stability features help on active job sites?

The dolly balances the need to move gear quickly with the need to lock it down for safe loading and use. Two front casters lock to make the setup stationary, while a friction brake keeps the dolly fixed while mounting boxes. Dual-wheel positions let you prioritize either compact interconnection or wider stance for single-unit stability.

• Front locking casters secure the unit for stationary tasks
• Brake pedal provides controlled, hands-free stopping during setup
• Inboard and outboard wheel placements adapt to connection or stability needs

How much weight can a single dolly handle and how does that affect use?

Each Klein Tools 54828MB supports up to 250 pounds, making a single dolly suitable for transporting heavy toolboxes, parts bins, or jobsite supplies. When dollies are interlocked, the combined platform raises capacity and footprint for larger material staging or multi-box transport.

• 250 lb single-dolly capacity for tools and materials
• Interlocked dollies increase overall load and surface area
• Designed for repeated professional use and rugged conditions

Who is this for? The Klein Tools 54828MB MODbox Caster Dolly is aimed at tradespeople, site supervisors, and mobile technicians who need a flexible, durable solution to move and organize toolboxes and supplies. It's ideal for crews who work in tight spaces or who regularly reconfigure staging areas — anyone who benefits from converting static storage into a lockable, wheeled workstation that can be expanded by snapping multiple dollies together.
