The MODbox tool box from Klein Tools helps to conveniently store your toolbox in one place. Durable 10” solid rubber wheels ensure smooth and neat movement over a variety of surfaces. Built-in side rails allow you to mount additional accessories, providing easy access to frequently used items and tools. The telescoping handle is fully removable for storage in tight spaces or transportation in a small vehicle. Long and awkwardly shaped items can be placed in the back of the system for convenient storage. The lid of the drawer has a V-shaped pipe slot with a molded ruler for easy measuring and a steel-reinforced place to attach a padlock or cable. The tool box is made of impact-resistant polymers, is IP65 rated and can withstand loads up to 250 lbs.
