Elongated instrument storage case with professional-grade design to safeguard your instruments.
IP67 fully sealed waterproof and dustproof design blocks moisture and dust: An integrated high-elastic rubber sealing ring is embedded at the case opening to form a seamless fit when latched. It repels rainwater on rainy days, construction site dust and damp mist in garages, preventing oxidation and rust of long metal wrenches, short circuits of elongated electronic devices caused by moisture, and dust contamination and scratches on lens glass.
Integrally molded thickened three-dimensional reinforcing ribs all around for waterproof, drop-resistant and deformation-proof performance: Raised anti-collision ribs are injection-molded as one piece across the case sides and top lid with no splicing gaps. The case resists cracking and denting after free falls from 1 meter and multi-layer stacking compression, fully protecting elongated tools and precision equipment from damage during vehicle vibration and rough courier sorting.
Independent front pressure balance relief valve enables easy case opening at high and low altitudes: The waterproof relief valve automatically equalizes air pressure inside and outside the case. Negative pressure that would suction the lid tight is avoided during air transport and temperature fluctuations on plateaus, eliminating the need for prying with force and allowing smooth opening during cross-regional long-distance transportation.
Anti-slip top carry handle tailored for the elongated body for effortless single-person transport: The empty case weighs only 2.1KG. The handle features anti-slip textures and multi-point rivet reinforcement, avoiding hand strain even when fully loaded with complete long-handled wrench sets and telephoto lenses. Its slim narrow profile fits neatly alongside car trunk edges and side pockets of outdoor backpacks.
Dual self-locking spring latches with anti-theft lock holes enhance safety during storage and transit: Symmetric thickened spring latches on both sides fasten tightly and will not pop open accidentally under vehicle vibration or manual carrying on foot. Standard padlock holes are reserved on latches for locking during long-term garage storage and logistics shipping to prevent loss of valuable precision elongated equipment.
Front classification nameplate slot for easy differentiation of stacked cases in warehouses: A red transparent label slot on the front allows custom insertion of classification tags, enabling quick identification of internal tool types when multiple elongated tool cases are stacked for streamlined management in auto repair and equipment warehouses.
Custom machined inner liners secure elongated items against shifting: Standard configuration includes wave-shaped cushion foam on the lid and a flat solid EVA base pad in the main compartment for loose storage of long wrenches, cables, elongated probes and other spare parts. CNC one-piece milled EVA liners are also available, precisely contoured to fit the shapes of elongated tools and lenses to eliminate shifting, friction and collision damage under transport vibration.
Wide-temperature weather-resistant modified material ensures long-lasting durability across all scenarios: UV-resistant and cold-resistant modifiers are blended into the raw material to maintain stable case performance from -30℃ to +80℃. The case resists brittling, whitening and deformation with long-term outdoor use in freezing northern open-air garages and sun-exposed southern environments.

Front Red Nameplate Slot
A red transparent label card slot is pre-installed on the front of the case, allowing free replacement of classification labels. When multiple long toolboxes are stacked neatly, the tools stored inside can be quickly distinguished, facilitating classified management in auto repair warehouses and equipment storage facilities.

Bilaterally Symmetric Thickened Self-Locking Spring Latches
The latches are made of thickened virgin engineering plastic with strong elasticity. The left-right symmetrical design ensures even force distribution, preventing loosening during vehicle vibration or construction site handling. Standard lock holes are reserved on the latches for installing anti-theft padlocks to enhance storage security.

Integrated Wave-Shock Absorbing Sponge on Case Lid
Formed wave-shaped sponge is built into the case lid. When the case is closed, it closely fits long spanners, lenses and instruments inside, effectively cushioning vibration and impact generated during driving and transportation, so as to prevent long articles from being scratched by friction and damaged by collision at both ends.

Integrated Anti-Slip Reinforced Top Handle
The handle is integrally mounted on the top surface of the case, featuring anti-slip concave-convex textures on its surface and reinforced by rivets at multiple positions. It resists cracking and deformation even when fully loaded with a complete set of long-handle hardware tools. Designed with an ergonomic curved grip surface, it prevents hand fatigue during prolonged field carrying.

Matte military black is available as standard stock, which is stain-resistant and scratch-proof. It effectively hides garage oil stains and outdoor dirt smudges. Custom colors such as military green, industrial orange and light gray can be arranged for bulk orders.
Custom Logo Engraving: Laser engraving and silk screen printing are supported on the case surface for auto repair shop logos, outdoor equipment brands and corporate equipment serial numbers.

Q1: What is the maximum length of tools that can fit inside this long case?
A: The usable internal length of the case is 430mm. Long wrenches, telephoto lenses and elongated detection equipment within the standard 400mm length can be placed directly inside. For extra-long items, you may contact us to customize an extended-length case.
Q2: Can the paper label inside the red label slot on the case surface be replaced?
A: Yes. The label slot adopts an open slot design. You can cut and print sorting slips by yourself to insert into the slot, making it easy to distinguish different stored items such as wrenches, lenses and testing instruments.
Q3: Can shoulder straps be installed through the hanging holes on both sides of the case?
A: Standard hanging holes are reserved at both ends of the case, allowing you to match shoulder strap accessories of the same specification. You can carry the case on your back during field hiking surveys and outdoor shooting to free your hands.
Q4: Will the sealing ring get moldy and deteriorate if the case is stored in a damp garage for a long time?
A: The sealing ring is made of corrosion-resistant natural rubber with an inbuilt mildew-proof formula, so it resists mold growth in damp garages and environments with light oil stains. It is recommended to open the case for ventilation once a month to extend its service life.
Q5: What is the minimum order quantity for custom EVA liners? Is it possible to only make slots for a single wrench?
A: The MOQ for custom liners is 300 pieces. We support custom separate slots according to the dimensions of long wrenches and lenses. You can provide physical samples or dimension drawings for us to develop molds and process the liners.
Q6: What is the maximum load capacity of the case handle? Will it break when fully loaded with heavy wrenches?
A: The riveted integrated handle can bear a maximum weight of 12KG. The total weight of a standard full set of automotive long wrenches is far below the load limit, so it will not break under normal carrying. Violent dragging and dropping the case from heights are prohibited.
Q7: Will worn anti-collision ribs on the case corners affect the waterproof sealing performance?
A: The outer anti-collision ribs are merely protective protrusions and do not come into contact with the inner sealing ring. Slight wear on the corners alone will not impair waterproof performance. However, severe deformation of the case frame will damage the seal, so heavy impacts should be avoided.
