I.Product Introduction
This medium-sized aluminum alloy protective toolbox has outer dimensions of 360×225×250mm and inner dimensions of 345×215×230mm, with a net box weight of 1.9KG. The box body features thickened aluminum alloy profile edging paired with wear-resistant smooth panels, reinforced by metal anti-collision corner guards at four corners, making it drop-resistant, pressure-resistant, rust-proof and oil-resistant. The box is standard-equipped with a double-layer cushioning structure consisting of three layers of tearable shock-absorbing foam and wave-shaped shockproof foam on the box lid, which can be freely grooved to secure precision instruments, measuring gauges, photographic equipment and complete sets of maintenance tools. The rigid shaped box is lightweight and durable, suitable for construction site maintenance, on-site equipment inspection, outdoor photography, household hardware storage and vehicle-mounted storage. It provides all-round shock absorption and buffering to effectively protect precision items from collision and scratch damage.
II. Core Selling Points
- Fully reinforced aluminum alloy frame, drop and impact resistant for construction site outdoor use.The frame is made of widened anodized aluminum alloy all around, with full-wrapped metal anti-collision corners on four sides. It resists deformation and cracking from ground impacts and stacking extrusion, featuring higher strength than plastic cases and durable for long-term heavy-load use at construction sites.
- Waterproof and wear-resistant panels, oil-resistant and easy to wipe cleanSmooth waterproof boards resist engine oil, dust and stains. Once dust or oil stains adhere to the surface, they can be wiped off completely with a damp cloth without leaving scratches. They are easy to maintain in greasy environments such as auto repair shops and construction sites.
- Large open compartment with flexible storage, compatible with items of various sizesThe smooth interior provides ample space to hold large tools and small precision equipment. Paired with tearable foam for custom compartment division, it meets both loose storage and precise positioning needs.
- Bimetallic spring latches, lockable for anti-theft and accidental opening preventionThickened metal buckles on both sides deliver tight fastening and will not pop open during running or vehicle bumping. Lock holes are reserved on the buckles, allowing padlocks to be fitted when storing heavy measuring tools and precision equipment at construction sites.
- The integrated top handle with rubber coating is reinforced by multiple rivets. It stably holds full loads of hardware tools and instruments. Weighing only 1.9KG in total, the device is light and labor-saving for on-site maintenance and field trips.
- Hard molded design provides dustproof and moisture-proof protection to preserve the precision of measuring tools.The rigid case offers full structural support. Unlike fabric bags that may squeeze precision calipers and testing instruments, it blocks construction site dust and moisture once closed, extending the service life of tools and equipment.

IV. Details Display
- Waterproof and Wear-resistant Smooth Panel
Its dense smooth surface resists scratches without leaving obvious marks. It is waterproof and oil-resistant. Water stains and oil smudges can be easily wiped clean, and the panel is not prone to rusting or absorbing stains.

- Double-sided self-locking metal spring bucklesMade of thickened stainless steel, the latches deliver strong spring force and fasten tightly without slipping off. Built-in lock holes allow padlocks to be fitted, offering safer storage for tools and instruments.

- Full Set Double-Layer Cushion Sponge
The wave foam on the top cover absorbs vibration and noise; the three-layer bottom sponge can be torn apart layer by layer, with customizable cut-out grooves for shaping. It features separate slots for various instruments and tools to prevent them from shifting around.

- Level the inner bin of the large through siloFlat compartment without internal partitions, allowing long tools, complete sets of hardware and small instruments to be laid flat for flexible loading with high space utilization.

IX.FAQ
Q1: Can the sponge be cut by oneself to fit tools?
A: The bottom layer consists of three layers of tearable sponge. You can peel off layers to carve out matching contours, which can firmly fix cameras, measuring tools and spanners without shaking or friction during unpacking.
Q2: Can small padlocks be fitted to the latches?
A: The double-side metal latches come with lock holes, allowing you to attach small padlocks separately for safer storage of high-value measuring tools and instruments at construction sites or when going out.
Q3: Is it easy to clean engine oil and cement dust off the case?
A: The waterproof glossy panel can be wiped directly with a cloth dipped in detergent without absorbing stains or leaving marks, making it easy to maintain for construction and auto repair work.
Q4: Can the sponge liner be replaced separately after wear and tear?
A: Replacement sponges can be purchased and delivered separately, so there is no need to replace the entire toolbox to cut long-term maintenance costs.
Q5: Will the handle break easily when carrying the box full of heavy tools?
A: The box features an aluminum frame with multi-point rivet reinforcement and an extra-thick metal handle. It can stably hold a full load of regular repair hardware without breaking or deforming easily.
Q6: Can a full set of socket wrenches and gear spanners fit inside?
A: The inner length is 345mm, which can hold standard short and medium socket wrenches and gear spanners flat. You may check the length of your tools before placing an order.
