Quality:  Chandler Truck Accessories' attention to detail starts with the box that contains the "box".  Before they are packaged each Chandler Equipment toolbox is wrapped in a self-stick film to reduce the possibility of scratching while being packaged.  Then, a 1" thick, high-density, foam block is placed at each corner to protect the highly vulnerable corners.  At the same time, those blocks create a 1" space between the toolbox and the shipping box which helps reduce damage from a light bump or the sharp corner of another package shipped on the same truck.  While it is virtually impossible to protect a package from being damaged through carelessness in shipping, Chandler's packaging addresses the most common damage-prone areas

Durable: Chandler Equipment's Toolboxes are designed with input from professionals that use under-bed toolboxes, every day, in the roughest environment - oil fields - Chandler Equipment used that input to produce the toughest underbody toolbox you can buy without breaking the budget. Start with robotically welded, 12 gauge U.S. Carbon steel for both the box and the door. Robot welding ensures a consistent weld and the jig mounting keeps the box perfectly square. Open the door and you will see a full powder coated-interior and two 3/16" HD drop chains because, after all, you know that the door is going to be used as a platform at some time and these HD chains are up to the task.

Weather Resistant: The design features don't stop with the box itself, though. Instead of inset doors, Chandler Truck Accessories mount the polished stainless steel doors for an external closure that enables them to build a 360 degree, full perimeter, 1" wide rain gutter so the water washes down and away. Any overflow is kept out by a full perimeter, automotive grade, replaceable, bulb seal, and water-resistance is enhanced further by the twist-to-lock T-Handle latch that pulls the door tightly against the seal. That T-Handle latch is adjustable so it will always pull the door tightly shut even after years of use.

Secure: The T-Handle latch has a built-in lock cylinder and for added protection, a loop for a padlock. Rather than weld the handle to the door it is bolted in place with 4 industrial "hucks". Each huck has a pull strength of 3,000 lbs, so you have 12,000 lbs. of protection against any attempt to pry the door open. The position of the hucks is not visible from the outside so drilling, externally, to gain access is virtually impossible.

Convenient: By using hucks for securing the latch and hinges means they are replaceable without cutting and re-welding. If the door should get damaged you just drill out the hucks and replace the door or the hinge in the field and without removing the toolbox. That's a very important feature if your boxes are welded in place. Inside the box, you'll see two 1" holes for draining that spilled oil or hydraulic fluid. Two snap-in plugs are included for easy access and sealing after draining.
