Standard padlock holes are pre-reserved on the latches, allowing users to lock the case for long-term storage of maintenance tools or logistics shipment to avoid tool loss.
High-Density Wavy Shock-Absorbing Sponge for Case Lid
Thickened high-density wavy sponge is attached to the case lid. When the case is closed, it fully fits the pliers, detectors and lenses inside. It cushions the impact from field handling and long-distance vehicle vibration, preventing metal tools from scratching the surfaces of precision instruments.
Triangular Three-Dimensional Anti-Collision Reinforcing Ribs All Around the Case
Integrally formed triangular raised anti-collision ribs are arranged on the top surface and side walls of the case to disperse impact forces generated by drops and stacking extrusion. The case maintains its shape under multi-layer stacking and resists deep scratches from hard objects at construction sites, thus extending its service life.
Standard in-stock version features a matte black body paired with red handles. The black surface resists oil stains and dirt, while the red handles offer high visibility, enabling quick identification of the toolbox at construction sites and maintenance workspaces. For bulk orders, case bodies can be customized in army green and industrial orange, with matching handle color adjustments available.

Q1: The case weighs 4 KG net. What is the maximum load capacity when fully loaded with plumbing and electrical tools? Will the handle break if the case is filled with heavy pipe wrenches?
A: The case is designed with a maximum full load capacity of 22 KG. The total weight of standard complete sets of electrical and plumbing tools falls within the load limit. The double-layer riveted red rubber handle can bear the full load weight. Do not lift only one side of the case or drag it violently.
Q2: Will water seep into the internal instruments if the case is soaked in rainwater after all three latches are fully fastened?
A: The case features an IP67 sealing rating, so no water ingress will occur during short-term rain exposure or shallow water immersion. It is only suitable for short-duration outdoor operations and cannot be fully submerged underwater for extended periods.
Q3: What are the dimensions of the label slot on the front of the case? Can printed PVC store labels be inserted into it?
A: The nameplate slot adopts a universal standard long strip size. You may cut your own paper or waterproof PVC labels for insertion. For bulk orders, you can contact the factory to pre-print custom store labels.
Q4: Will the sealing rubber ring get moldy easily if the case is stored long-term in damp basements?
A: The rubber ring is formulated with anti-mold and bacteriostatic agents, so mold growth is unlikely during short-term basement storage. It is recommended to open the lid for ventilation every two weeks and wipe off moisture and oil stains on the rubber ring surface monthly to extend its sealing service life.
Q5: Can replacement matching wave foam liners be purchased separately?
A: Separate purchases of lid wave foam and one-piece molded EVA liners are available. You do not need to place an order for a full case set. Provide the product model to request a separate quotation and arrange shipment.
Q6: Will the plastic latches snap off when bent during outdoor emergency repairs at sub-zero temperatures in northern winters?
A: Cold-resistant modifiers are added to the raw materials of the case and latches, which maintain toughness at temperatures as low as -30°C. Avoid forcefully snapping the latches abruptly in low-temperature environments; slow opening and closing can prevent damage caused by cold brittleness.
Q7: The triangular reinforcing ribs protrude from the side of the case. Will stacking multiple cases scratch the paint finish of the lower ones?
A: The edges of the anti-collision ribs are rounded and passivated. Only the ribs make contact with the flat surface of the lower case during stacking, so the matte shell will not be scratched. A layer of soft foam padding between each layer is recommended for long-term multi-layer stacking protection.
