If you searched for Waterproof portable-tool-box Wholesale, you probably have a specific use case in mind — not the generic 'protective case'. We have built 150+ custom variations since 2014. Here is what we know.
For your reference, here are the WL series models we typically use for Waterproof portable-tool-box Wholesale applications. Outer dimensions (OD) are measured to the outside of the case; inner dimensions (ID) reflect the usable cavity after subtracting wall thickness. All in millimeters; imperial dimensions in our catalog PDF.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP+GF | Electrician Tool Kit |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP+GF | Plumber Tool Kit |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+GF | Auto Mechanic Trolley |
The most common model for "Waterproof portable-tool-box Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+GF body).
All Waterproof portable-tool-box Wholesale cases use engineering-grade polypropylene (PP) or PP+glass-fiber composite (PP+GF) for the shell, with CNC-cut closed-cell PE foam inside (density 25 kg/m³). The foam density is calibrated to absorb 1.2m drops on concrete while keeping your equipment from shifting.
The shell is rated IP65 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.2m). Temperature range is -40 ~ +80 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
Our Waterproof portable-tool-box Wholesale buyers in 2024 include: 35% camera operators / filmmakers, 25% drone pilots / commercial UAS, 15% broadcast / TV stations, 10% military / law enforcement, 10% medical / first responders, 5% industrial / OEM. Profile data from 2024 buyer survey.
Cheap Waterproof portable-tool-box Wholesale: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our Waterproof portable-tool-box Wholesale: $5-15/unit, 10-year lifespan, 5,000-cycle latch, 25 kg/m³ foam. Over 5 years, our case is 4-5x cheaper per year of use. Total cost of ownership wins.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
After Waterproof portable-tool-box Wholesale ships: (1) We send QC photos before shipment. (2) Lot certificate with serial numbers. (3) 90-day defect replacement. (4) Foam re-cut service for equipment changes. (5) 5-year case body warranty. (6) Tooling stored 3 years for easy reorder.
We do not charge extra for long-tail specs. Standard WL series pricing applies unless the spec requires a new mold.
