Buyers Products 1705285 Silver Smooth Aluminum WideOpen Class 8 Step Box, 16.25 x 36.25 x 23.3 Inch, Frame Steps with Built in Side Storage, Locking Die-cast Compression Latch, Semi-Truck Tool Box

Buyers Products WideOpen Class 8 Step Boxes combine spacious side storage with a sure-footed step for professional drivers. Made in the USA from durable 0.125 in smooth aluminum, each box is built to stand up to vibration, road spray, and daily use while keeping weight down on your tractor. The WideOpen lid swings extra wide so you can stow larger items and reach tools quickly without fighting a narrow opening. A corrosion-resistant stainless steel hinge and stainless hardware are designed for long-term reliability. To help keep gear clean and dry, an automotive bulb seal helps keep out water and dirt, and the polished stainless steel locking T-handle compression latch adds security when you are away from the truck. The step surface uses replaceable grip strut tread for excellent traction in wet or icy conditions, and the tread can be swapped as it wears to keep performance consistent. Universal fitment supports Peterbilt, Kenworth, International, Freightliner, Western Star, Volvo, and Mack. For boxes wider than 18 inches, Buyers Products recommends using 1701015 steel mounting brackets to reduce stress and help prevent cracks over time.

• ULTRA-WIDE ACCESS DESIGN: Extra-wide opening lid provides fast, comfortable reach to tools and gear, so drivers can load bulky equipment and grab essentials without tight angles, pinched hands, or wasted time.
• INTEGRATED STEP WITH TRACTION: Replaceable grip strut step surface delivers confident footing in rain, snow, mud, and oil; when the tread wears, swap the step insert to keep safe traction season after season.
• HEAVY-DUTY ALUMINUM BUILD: Built from rugged 0.125 in smooth aluminum to handle road vibration, salt, and impacts while staying lightweight to help reduce added frame load and support everyday fleet durability.
• SECURE & WEATHER-RESISTANT: Automotive bulb seal helps block water and dust, while the polished stainless steel T-handle compression latch locks down tight to deter theft and protect cargo from harsh weather.
• UNIVERSAL FRAME-RAIL FIT: Fits major Class 8 brands including Peterbilt, Kenworth, International, Freightliner, Western Star, Volvo, and Mack; installs on frame rails, and boxes wider than 18 in should use 1701015 brackets.
