FAQ
- How does the lock body protect the keyhole from rainwater, mud, and tampering?
- The lock features a reinforced steel shroud that completely surrounds and shields the keyhole and shackle, leaving no exposed metal for prying tools to grip. A built-in rubber keyhole cover prevents rainwater, dust, and grime from entering the cylinder, ensuring reliable operation in all weather conditions from monsoons to desert dust storms.
- Will the lock rust in tropical humidity or salt air near the coast? What is the expected lifespan?
- The lock body undergoes a triple-layer protection process: shot-blasted base steel + hot-dip zinc plating + marine-grade powder coat topcoat. This is the same standard applied to offshore equipment, giving a corrosion resistance of ASTM B117 1,000+ hours in salt spray testing. Expected service life is 8-12 years in tropical coastal environments.
- Will the lock cylinder seize or the key bend in the 50 degree centigrade + heat of Saudi Arabia or the UAE?
- Our lock cylinders use precision-engineered brass pins with tight sand-proof tolerances, lubricated with high-temperature synthetic grease rated to +120 degree centigrade. The key is made of stainless steel (not standard zinc alloy) to eliminate bending under torque in high-heat conditions, ensuring consistent, frustration-free operation year-round.
- Does this lock fit all types of container doors, including high-cube and reefer containers?
- Yes. The lock is designed to clamp onto the standard vertical locking rod (cam rod) found on all ISO dry containers, high-cube boxes, and reefer containers. The adjustable jaw width accommodates rod diameters from 28mm to 42mm, covering virtually all container door lock rod standards in global use.
- Is this lock only for shipping containers? Can it secure truck cargo doors or warehouse gates?
- It is highly versatile. Beyond standard ISO shipping containers, it is widely used to secure truck trailers, temperature-controlled reefer trucks, storage yard gates, and self-storage units. Any application involving a vertical locking rod or standard hasp is compatible, making it a one-lock solution for your entire logistics security chain.
