Choosing the right box and door finish for your new step tool box big mouth is all about taste and style. An aluminum checker-plate finish will give you a polished look and road wear & tear will be less visible on this type of finish. While a plain aluminum box with plain doors will have a smooth finish look and will suit any type of truck finish.

Find the feature of the selected product below.


Step tool box big mouth-BODY FINISH AND DOOR FINISH

Our standard aluminum plain option is a toolbox made of 1/8 (.125) thick plain aluminum. This mill finish is the surface texture (or finish) of this toolbox. This texture is smooth and lacks luster. Some prefer this because it has a uniform finish and is easy to polish. It is also the # 1 choice if you want to have it painted. This finish will go well with any truck finish and is a great replacement for the checker-plate finish if the checker-plate is not your preferred style. This smooth finish will look great on any truck or trailer!

** Note that we do not offer painting or polishing services. **


Step tool box big mouth'-'DOOR OPTION

Step tool box big mouth - Trebor’s semi-truck top lid tool box can easily be mounted and gives you maximum storage.

Top lid truck boxes are practical for storing tools such as your straps, chains , binders, hitching , unhitching tools , like crowbars, lift jacks, box wrenches, hitch balls and much more. This is most commonly installed on the rails of your semi-truck. This model comes with a larger opening as well as a door retainer cylinder.

The knock on step boxes has always been the box opening is so small you were limited on what could be stored in them, but not anymore with the Trebor big mouth. The entire front and top portion now open making a much larger opening where more can be stored.

T-Handle Handle

Our signature Trebor T-handle is one of our most popular and cost-effective handle options with a key lock. This handle has a stainless-steel finish and offers a unique shine. This handle must be lifted and then turned in order to open the door. There is also a small cap above the lock to protect the entry of the key from weather, dust and debris. This T-handle is installed with stainless steel rivets.


Step tool box big mouth'-'HINGE(S)

Piano Hinges

Piano hinges are the best option for your top lid truck tool box. These stainless-steel hinges are very practical and durable and are made specifically for top cover heavy duty boxes. All piano hinges are installed with stainless steel rivets.


Step tool box big mouth'-'SEAL

It’s important to have a tool box for your truck, but what's even more important is to have a box that keeps your equipment dry. This is why Trebor manufacturing offers a door seal on the frame. This seal compresses during closing and allows to take its expansion for its sealing.
