This BETTER BUILT Saddle Truck Tool Box is constructed of heavy duty diamond tread plate aluminum and will never rust. The stainless steel paddle handle latches feature double static cams that guide the lid striker into the lock, allowing you to easily open the truck box while providing maximum security. Auto-lift, self-rising, gas powered shocks allow for easy, single handed entry in to the box. The self-adjusting striker accommodates for any misalignment between the lid striker and the latch to ensure the lid closes securely every time. The deep design provides maximum storage space for larger items. Crossover boxes are designed with patented integral ends, which means the end of the truck box is made of a solid piece of metal, adding strength and creating a small parts storage area. The tub of the box is constructed from one piece of metal, which creates less welds and gives the box added strength. The lid features a reinforced metal lid brace for added strength and a full perimeter closed-cell weather resistant seal to protect your truck box contents from dirt and moisture. The patented up-and-over rod moves the locking system away from the working space of the box, keeping it from being damaged.
