PP material, suitable for both commercial and engineering use, with thickened safety protection.
This dual-purpose hard protective case for business and engineering use has external dimensions of 475*380*140mm, internal dimensions of 445*325*132mm, and a net weight of 2.45KG. The case body is integrally injection-molded from high-toughness polypropylene (PP) material, equipped with a full set of shockproof inner liners consisting of wavy cushion top foam and tear-to-shape bottom foam. It balances an elegant business appearance with industrial-grade drop and water resistance. Featuring a double-latch locking structure and sealing rubber ring, it delivers multi-layer protection against water, dust, shocks and compression. Custom-designed for precision testing instruments, business samples, photographic equipment and complete maintenance tool sets, it is suitable for transporting equipment in laboratories and on construction field trips as well as carrying samples during business trips. Combining professional protection with a minimalist business look, it serves as a universal storage and protective case for government and enterprise testing institutions, engineering maintenance teams and photography studios.
Vertical textured business appearance with industrial-grade heavy-duty 2-in-1 protection: The case features a delicate matte panel with vertical stripes on its surface, delivering an understated business aesthetic ideal for business exhibitions and business trips with samples. Equipped with thickened shock-absorbing foam inside and sealing gaskets, it is waterproof and drop-resistant, remaining durable even under harsh working conditions at construction sites and in the wild.
Dual-layer shock-absorbing foam offers all-round protection for equipment: The case lid is integrated with wave-shaped sound-absorbing shock padding, while the case bottom holds thickened tearable layered foam. Custom grooves can be freely carved to fit the shapes of instruments, lenses and tools. The foam wraps items for cushioning during bumpy transportation, preventing collisions, scratches and displacement to preserve the precision of delicate equipment.
Sealed dustproof and waterproof structure ensures stable performance across diverse environments: A full circle of highly elastic rubber sealing strips is embedded along the case opening for a gapless closure, blocking rainwater, dust and construction site grease. Instruments stored outdoors on rainy days or in humid workshops stay free of dust and moisture.
Ergonomic non-slip carrying handle ensures comfortable, labor-free lifting under heavy loads: The widened central rubber non-slip handle is reinforced with multi-point rivets. It avoids hand soreness and breakage even when fully loaded with complete sets of instruments and tools, enabling effortless long-distance carrying by a single field worker.
Weather-resistant, anti-aging wide-temperature material delivers long-lasting durability for all scenarios: Made of polypropylene blended with UV-resistant and cold-resistant modifiers, the material resists brittleness and deformation in temperatures ranging from -30℃ to +80℃, supporting long-term stable use in frigid northern outdoor areas and sun-exposed southern workshops.

Delicate Vertical Grain Business Panel
The entire cabinet body features vertical anti-slip textures with an elegant and timeless matte black finish that resists scratches and fingerprint smudges. It maintains a sleek refined look for business scenarios, and engineering grease and stains can be easily wiped off for cleaning.
Double-layer full-set shock-absorbing foam lining
The wave foam on the top cover absorbs vibration and noise, and the tearable foam at the bottom can be freely layered and grooved. Instruments, lenses, wrenches and accessories can all be precisely positioned without shaking or rubbing against each other.
Reserved Groove for Metal Nameplate
A nameplate mounting position is reserved in the center of the front of the cabinet, where custom metal LOGOs, equipment serial numbers and department names can be installed, enabling clear classification of multiple cabinets during warehousing.
Widened anti-slip integrated handle
Multi-point reinforced riveting ensures even force distribution, making it resistant to breakage under full heavy loads. The rubber anti-slip texture fits snugly against palms, preventing hand soreness and slipping even after prolonged carrying.
Matte Business Black is regularly in stock, a stain-resistant color scheme widely used for business and engineering scenarios. Custom cabinet colors including military green, dark gray and orange are available for bulk orders.
LOGO Marking: laser engraving on the box, screen printing of store LOGOs, brand logos and tool serial numbers;
Custom Grooving for Inner Liner: exclusive slots are milled via CNC machining according to the specifications of gear wrenches and sockets, securing each set of tools in place to prevent shifting. Tearable sponge allows free grooving and layout adjustment;
