Waterproof and drop-resistant toolbox made of PP material, customizable inner protective liners available!
IP67 fully sealed waterproof and dustproof design to block erosion from moisture and dust:
An integrated high-elastic rubber sealing ring is embedded around the case opening, creating a seamless fit with the case body once latched. It effectively repels moisture and dust in scenarios such as outdoor rain exposure, construction site dust, humid workshops and high-humidity coastal environments, preventing oxidation and rust of metal tools, damp-induced malfunctions of electronic instruments, as well as dust ingress and scratch damage to optical lenses.
Integrally formed three-dimensional thickened anti-collision ribs all around for superior drop resistance and deformation resistance:
Widened protruding anti-collision ribs are molded as one piece across the top surface and all side walls without spliced gaps. The case will not crack or dent after free falls from 1.2 meters or heavy pressure from multi-layer stacking, fully safeguarding internal equipment against bumps during field work and rough sorting by couriers.
Front-mounted pressure balance relief valve for smooth opening at all altitudes:
The waterproof relief valve automatically equalizes air pressure inside and outside the case. It avoids negative pressure that would suction the lid shut during cross-border air transport and high-altitude field operations, eliminating the need for forced prying and enabling effortless lid opening during long-distance cross-regional transit.
Integrated non-slip front handle for effortless single-person field transport:
The empty case weighs only 3.25KG. The handle features textured anti-slip indentations and multi-point reinforced rivets, so carrying fully loaded tool sets and photographic gear causes no hand strain. Its square shape allows stable placement in car trunks, workbenches and alongside outdoor backpacks.
Double-sided self-locking thickened spring latches with anti-theft lock holes for dual safety in storage and transit:
Symmetric widened spring latches on both sides fasten tightly without loosening, preventing accidental popping open amid vehicle jolts or walking movement. Standard padlock holes are reserved on latches to fit padlocks for in-store storage and long-distance logistics shipping, lowering the risk of loss for valuable precision equipment.
Red nameplate slot on the front for clear categorization of stacked cases in warehouses:
An open red transparent label slot on the front allows customizable paper classification labels to be inserted. Multiple stacked cases can be quickly sorted by contents such as tools, instruments and photographic gear, boosting bulk warehouse management efficiency.
Optional customizable inner liners to secure equipment free of shifting:
Two standard liner options are available: an empty large open compartment and a wave-shaped sponge kit. Custom CNC one-piece grooved EVA liners can be tailored to precisely fit the contours of wrenches, testing meters and camera lenses, keeping items fixed without displacement, friction, scratches or impacts amid transit vibrations.
Wide-temperature weather-resistant modified raw materials for long-term durability across all regions:
UV-resistant and cold-resistant modifiers are blended into the material to maintain stable case performance between -30℃ and +80℃. The case resists brittling, whitening and deformation after prolonged use in open-air construction sites during frigid northern winters and sun-baked vehicle compartments in sweltering southern summers.

Front Red Classification Identification Nameplate Slot
A red transparent label card slot is pre-installed on the front of the case, allowing freely cuttable and replaceable classification slips. When multiple toolboxes are stacked neatly, stored items inside can be quickly distinguished, enabling clear and convenient classified management for workshop storage and equipment warehouses.

Double-Sided Symmetric Thickened Self-Locking Spring Latches
The thickened virgin engineering plastic latches are symmetrically arranged for even force distribution, preventing loosening during vehicle transportation bumping and construction site handling. Standard lock holes are pre-reserved on the latches for installing anti-theft padlocks to enhance the storage safety of valuable instruments.

Integrally Formed Wave-Shaped Shock-Absorbing Sponge for Case Lid
The optional case lid is lined with high-density wave-shaped sponge. When the case is closed, the sponge closely fits the internal tools, lenses and testing meters. It cushions vibration and impact forces generated during field handling and long-distance transportation, preventing scratches caused by mutual friction and edge damage from collisions.

Built-in Anti-Slip Reinforced Front Carry Handle
The integrated handle is embedded on the front of the case with concave-convex anti-slip textures on its surface and reinforced by rivets at multiple positions. It resists breakage and deformation even when fully loaded with complete maintenance equipment. Its ergonomic curved grip prevents soreness and fatigue in hands after prolonged carrying during field operations.

Matte military black is available as standard stock, which is stain-resistant and scratch-proof. It hardly retains or shows workshop engine oil, outdoor mud and dirt stains. Custom colors such as military green, industrial orange and light gray can be offered for bulk orders.

Q1: The internal height of this case is 195mm. What is the maximum height of vertical equipment that can fit inside?
A: The clear internal height is 195mm. After deducting the space occupied by the bottom EVA cushion, vertical instruments and lenses with a maximum height of 180mm or below can be placed inside. For extra-tall equipment, you may contact us for larger-size models.
Q2: Will the raised ribs on the back of the case scratch the surface of the lower case when stacked?
A: The raised ribs on the top of the case adopt a rounded-corner design. Only the ribs will touch the flat surface of the lower case during stacking, so the matte shell of the case will not be scratched. The appearance can remain intact even after long-term stacking.
Q3: Sand and silt have entered the pressure relief valve and caused a blockage. What are the simple cleaning methods?
A: Unscrew the outer knob of the pressure relief valve, rinse the internal filter screen with clean water, and reinstall it onto the case after it is completely dried. Do not poke the filter screen with sharp hard objects to prevent damage to the waterproof structure.
Q4: Can I cut sponge by myself and lay it inside the empty case model for use?
A: The inner compartment is flat without protruding partitions. You can purchase high-density sponge separately and cut it to size as needed for laying. If precise positioning is required, customized integrated EVA liners manufactured by our factory are more recommended.
Q5: Will the spring elasticity of the latches decrease significantly after tens of thousands of opening and closing cycles?
A: The latches are equipped with thickened industrial springs. There will be no obvious loss of elasticity within 30,000 routine opening and closing operations. For frequent opening and closing under long-term heavy loads, replacement latch accessories can be purchased separately.
Q6: Will the case surface fade and turn white if exposed to outdoor sunlight for a long time?
A: Anti-UV weather-resistant additives are added to the raw materials. No obvious whitening or fading will occur after 1 to 2 years of regular outdoor use. If the case is exposed to continuous midday sunlight for an extended period, store it in a cool place to extend the service life of its appearance.
Q7: Will the airtight interior of the case pose potential safety hazards if I store testing instruments with batteries inside?
A: The case is fitted with a pressure relief valve to balance internal air pressure. There are no safety risks when properly storing compliant lithium batteries. Do not store damaged or swollen batteries, and avoid placing the case in high-temperature airtight environments.
