Manufacturing FAQ's

1. What is a continuous hinge on Roadrunner Toolboxes?

Known as our "forever hinge" it is unique where by the hinge is run the entire side of the toolbox spreading the load weight of the door across the whole side of the door and box body giving it superior strength. Additionally the hinge is easily greaseable ensuring the hinge will not fail. Toolbox FAQ Images

2. What is a locking T Handle?

A top quality stainless steel latch with a foldable T-bar style handle that is folded away into a recessed cavity with in the latch and Locked with a key in a separate barrel. They are easily replaceable if damaged and have been tested to meet our quality standards for NZ conditions and security. Latches FAQ

3. Are Roadrunner Toolboxes sealed?

We use a folded channel design that not only adds strength to our boxes but creates a "gutter" so any rain and mud can easily drain off the box. We add a condensed sponge rubber to the door so that when the door is closed and locked it compresses against outer gutter and creates a weather tight seal.
