Product Introduction
This elevated three-proof handheld safety protective case for workshops features external dimensions of 450*395*290 mm (17.7*15.5*11.4in) and internal dimensions of 430*335*277 mm (16.9*13.1*10.9 in). The net weight of the case body is 3.9 kg, while the outer packing dimensions measure 480*435*330 mm (18.8*17.1*12.9 in).
The case body is integrally high-pressure injection-molded from thickened modified PP polypropylene. Equipped with multiple self-locking spring latches and a full-circumference rubber sealing strip on the lid, it meets the IP67 protection rating for waterproof, dustproof and shockproof performance.
The extra-high and deep inner compartment supports optional accessories as required, including wave-shaped shock-absorbing foam for the lid, layered tearable EVA foam, and CNC one-piece custom-fitted liners. It is ideal for storing complete sets of workshop maintenance tools, precision machined components, small testing instruments, laboratory sampling equipment and electronic components.
The heightened inner cavity accommodates tall-sized workpieces. Its integrated handle design facilitates workshop circulation, field quality inspection, warehouse storage and express delivery transit. Dual protection from sealing and cushioning prevents precision parts from bumps, scratches, moisture damage and oxidation rust.
Core Selling Points
Extra High & Deep Inner Cavity for Full Storage of Tall Workpieces
Boasting an elevated and deepened inner space, this case differs from standard shallow toolboxes. Extended measuring tools, tall machined parts and vertical testing instruments can stand upright without tilting or squeezing. Large and small items can be stored in separate layers, delivering superior adaptability for workshop handling and storage.
Integrated Thickened Grid Injection-Molded Shell – Heavy-Duty, Drop & Abrasion Resistant for Workshop Use
The top and all sides of the case feature three-dimensional crisscross grid reinforcing ribs, with integrated raised anti-collision corner bumpers. It resists dents and cracks when dropped from workshop heights, stacked by forklifts or knocked against workpieces. The matte scratch-resistant shell wipes clean of cutting oil and metal dust effortlessly, resisting aging and damage after long-term workshop service.
Dual-Side Self-Locking Spring Latches – Secure Fastening Against Accidental Pop-Open
Two sets of thickened spring latches are symmetrically fitted on both sides. They open and close quickly with one-handed pressing and will not spring open during bumpy workshop transit or stacked storage. Each latch comes with a standard padlock hole, allowing locked storage of valuable precision parts and testing instruments to prevent loss.
Spacious Organized Inner Compartment – Freely Configurable Cushion Foam for Zoned Storage
The extra-high, wide and deep main cavity offers ample depth to lay out complete measuring tool sets, hardware fittings and electronic components neatly. Optional cushion foam can be freely cut and grooved to create individual slots for parts and gauges. This eliminates sliding and friction during transit to stop scratches and surface damage to workpieces.
Built-In Waterproof Pressure Equalization Valve for Smooth Opening After Long-Distance Shipment
A concealed waterproof pressure relief valve on the side automatically balances air pressure inside and outside the case. It prevents the lid from being stuck tight by negative pressure during cross-regional inspection delivery, air freight, or extreme temperature shifts, enabling effortless opening for quality inspection and field sampling trips.

Symmetric Dual-Side Self-Locking Spring Latches
Two sets of thickened spring latches are symmetrically installed on both sides of the case. Simple to open and close, they automatically spring back and lock tightly after fastening without loosening. Each latch is designed with a reserved padlock hole. You may attach a padlock to securely store valuable machined parts and high-precision measuring tools.
Optional Full Set of Double-Layer Shock-Absorbing Foam
The wave-shaped shock-absorbing foam on the top lid absorbs vibration and cushions impacts. The layered tearable EVA foam at the bottom can be freely cut and grooved to create separate slots for machined parts, measuring tools and test probes. It completely prevents sliding friction that would scratch workpiece surfaces and measuring probes during transit.
Integrated Reinforced Anti-Slip Top Handle
An extra-wide handle is integrally injection-molded at the center of the case top. It features a broad curved anti-slip grip that stays distortion-free even when fully loaded with complete measuring tools and components. It delivers labor-saving and comfortable holding for short-distance workshop transfers and single-person inspection transport.
Extra-High, Deep & Spacious Main Compartment
The heightened, deep and roomy inner cavity allows vertical measuring tools and tall workpieces to stand upright without tilting. Full sets of workshop maintenance tools and electronic components can be laid flat neatly, while small fittings are stored in separate zones for tidy and organized warehouse storage and on-site handling.

Material and Process Description
Main Case Material
Thickened modified polypropylene (PP), integrally formed by high-pressure injection molding. The case delivers outstanding impact resistance, waterproof and moisture-proof performance, as well as tolerance to cutting oil and extreme temperatures. It resists aging, brittleness and deformation even after long-term workshop use.
Sealing Gasket
Made of high-elastic natural rubber. It maintains tight adhesion to the case after tens of thousands of opening-closing cycles, ensuring consistent long-term waterproof and dustproof protection without performance degradation.
Metal Hardware Fittings
Internal metal springs of hinges and latches undergo electroplating anti-rust treatment. They are resistant to rust and jamming under workshop conditions filled with metal dust and cutting fluid.
Molding Technology
One-piece high-pressure injection molding creates seamless construction. The integrated structure eliminates risks of water seepage and dust ingress via split joints, offering superior protection compared to basic aluminum storage cases.
Liner Processing Technology
- Lid wave foam: integrally hot-pressed molded
- Bottom tearable EVA foam: separable layers for custom slot layout adjustment
- Custom CNC milled liners: precisely contoured slots to perfectly match the outlines of parts and measuring tools

FAQ
Q1：Can this elevated case store extended calipers and tall machined parts vertically?
A：The internal height reaches 230 mm. Standard extended calipers, medium-small vertical testing instruments and tall machined samples can all be placed upright without squeezing or tilting.
Q2：Is the case dust-proof and resistant to cutting fluid? Is it applicable to machining workshops?
A：The lid is fitted with a full-circumference rubber sealing strip that meets IP67 waterproof and dustproof rating. It can effectively block splashing cutting fluid and metal dust in machining workshops, safeguarding precision parts and measuring tools stored inside.
Q3：What is the function of the pressure equalization valve?
A：Pressure difference will form between the inside and outside of the case during cross-regional courier delivery for inspection or in laboratories with extreme temperature changes. The valve automatically equalizes air pressure, preventing the lid from being tightly sucked shut by negative pressure. It facilitates easy opening when taking samples out of the workshop for inspection.
Q4：Can the bottom sponge be freely cut to fit the shapes of parts and measuring tools?
A：The bottom liner is layered tearable sponge. You can carve out contours matching workpieces, calipers and probes as needed to firmly secure precision components. No sliding friction will occur during transit to prevent scratches on workpiece surfaces and measuring faces.
Q5：Will the top handle break easily when fully loaded with complete measuring tools and parts?
A：The handle is integrally injection-molded with the case and widened & thickened for reinforcement. It can bear the full weight of loaded tools and workpieces, and is resistant to breakage and deformation during routine single-person handling and transfer in workshops.
Q6：Will precision parts shift and bump against each other if placed directly inside the empty case?
A：The empty case is only suitable for temporary loose storage. When equipped with matching tearable sponge or custom CNC contoured foam with cut-out slots, parts and measuring tools will be fully secured without shifting, friction, bumps or scratches during transit.
