Small instrument protective case, moderately sized, and widely applicable.
This medium-sized hard plastic safety protective toolbox is specially designed for ratchet tool box, socket sets, ratchet tools and small maintenance equipment. Its external dimensions are 430*345*155mm, internal dimensions are 405*295*143mm, and the net weight of the box body is 3.05KG. It is integrally injection-molded with modified high-strength PP engineering plastic, equipped with an IP67-rated sealing rubber ring, double safety latches and an air pressure balance valve structure, delivering multi-layer protection including waterproof, dustproof, shockproof and pressure-resistant performance. The empty box allows loose storage of tools, and tearable foam or CNC integrally formed EVA lining can be installed to secure complete sets of ratchet tool box, accessories and measuring tools with precise positioning slots. Applicable to multiple scenarios such as automobile maintenance, electrical overhaul, outdoor work and vehicle-mounted storage, it serves as a long-lasting and durable storage solution for professional mechanics and tool enthusiasts.
IP67-rated sealed protection to resist corrosion in oily and greasy environments. An integrated high-elastic rubber sealing ring is embedded at the box opening for a tight, seamless closure, blocking splashing water, engine oil and sediment from entering. In damp, greasy settings such as garages and construction sites, the internal tools stay clean; the box surface can be easily wiped clean, eliminating the drawbacks of ordinary tool bags that are prone to mildew and damage.
Built-in air pressure balance valve for smooth opening amid temperature fluctuations. The integrated waterproof pressure relief valve automatically equalizes air pressure inside and outside the case. It prevents negative pressure from sucking the lid tight during seasonal temperature shifts or long-distance shipping, so no brute force prying is needed for hassle-free cross-regional transport and easy lid opening.
Ergonomic portable design for comfortable heavy-load carrying without hand strain. A non-slip reinforced handle is embedded in the middle of the box to distribute weight evenly, keeping the case free of deformation even when fully loaded with a complete tool set. Its optimized lightweight structure makes it convenient for single-person outdoor work and on-site maintenance visits.
Dual latches with lock holes for secure tool storage against theft and accidental opening. Self-locking spring latches on both sides fasten firmly and will not pop open unexpectedly during vehicle travel or carrying while moving. Lock holes are reserved on the latches for padlocks, which can be fitted when storing tools at repair shops or working on external construction sites to avoid loss of valuable tools.
Customizable inner lining for organized storage of complete tool sets with zero shifting. Loose wrenches and fittings can be freely arranged in the empty case. EVA foam inserts can be customized with cutouts sized for ratchet tool box and sockets to hold tools in divided slots for instant visibility during access, preventing displacement, friction and collisions during transportation.

Independent Waterproof Pressure Relief Valve
The valve comes with an integrated waterproof structure that preserves the sealing performance of the enclosure. It automatically balances internal and external air pressure, enabling effortless opening of boxes during air transportation or in high-altitude regions.
Reinforced Integrated Handle
Multi-point riveting fixation ensures even force distribution, preventing breakage or deformation even when fully loaded with tools. The ergonomic grip curve fits the palm, reducing fatigue during prolonged carrying.
Continuous Extended Anti-Rust Hinge
The integrated one-piece hinge connects the box body and lid, featuring a wide opening angle for convenient tool access. It resists loosening and breakage even after tens of thousands of opening and closing cycles.
Organize the interior space of the general warehouse
Flat inner compartment without partitions for high space utilization; multiple sets of ratchet tool box and accessories can be neatly stored simultaneously, suitable for storing tools of various sizes.
Standard in-stock matte military black is stain-resistant and wear-resistant, concealing grime well in greasy auto repair environments. Custom box colors including military green, orange and gray are available for bulk orders.
Custom Logo Engraving: Laser engraving and screen printing of store logos, brand marks and tool numbers on box surfaces.
Precisely Grooved Inner Liners: CNC-machined exclusive slots tailored to sizes of ratchet tool box and sockets for a perfect fit with tool contours. Tearable foam allows free layering and custom cutouts to adjust internal layout.
Optional Expandable Accessories: Shoulder strap buckles and portable carrying straps can be fitted for large-quantity orders to support field work via shoulder carrying.
Bulk Group Procurement Cooperation: Auto repair shops, maintenance teams and hardware distributors purchasing in bulk qualify for tiered wholesale pricing, with official VAT invoices available.
Storage for auto repair and maintenance tools: Store complete sets of ratchet tool box, ratchet sockets and torque wrenches in one place for garage and vehicle transport, with protection against oil stains and bumps;
On-site electrical and plumbing maintenance: Store complete sets of screwdrivers, pliers and testing tools for easy carrying during on-site visits, with waterproof and sandproof performance for construction sites;
Protection for precision small measuring tools: Carry vernier calipers, torque testers and compact testing devices for field work, with shockproof design to preserve measurement accuracy;
Outdoor exploration / equipment maintenance: Portable protection for field operation tools, delivering reliable performance during rain exposure and bumpy transportation;
Vehicle spare tools: Secure storage in car trunks to prevent tools from rattling or scattering when driving over bumpy roads;
Long-distance courier delivery of valuable tools: Hard cases resist rough squeezing during sorting and drastically reduce tool damage rates in transit.

Q1: Can this box hold a complete set of ratchet wrenches and socket sets?
A: The standard inner compartment measures 405×295×143mm. A full regular set of ratchet wrenches and socket sets can be laid flat for storage. You may check the dimensions of your tools before placing an order.
Q2: Can a small padlock be fitted to the latches?
A: The latches come with standard lock holes, allowing you to install small padlocks as needed. It provides better anti-theft protection for tool storage in repair shops or outdoor construction work.
Q3: Is it easy to clean motor oil stains off the box?
A: The box features a smooth, wear-resistant surface. Oil stains can be wiped clean effortlessly with a cloth dampened with detergent without oil penetration or residue, making it easy to maintain for long-term auto repair use.
Q4: Will the box turn hard and brittle under low temperatures in northern winters?
A: The box is made of cold-resistant modified PP material. It maintains good toughness even at -30°C, so it can be used normally for outdoor winter operations without cracking upon impact.
Q5: Will wrenches rattle around inside an empty box?
A: Tools will only be loosely placed in an empty box. Custom milled EVA foam is recommended, with cutouts shaped to fit each wrench to fully eliminate shifting, shaking and scratch damage caused by friction.
