FAQ
Q: How does this twist lock operate?
A: The locking head is placed into the ISO 1161 corner casting, then rotated 90° using the solid operating rod. The hourglass-shaped head locks firmly into the casting opening, and the same rod releases it quickly when the container needs to be lifted off.
Q: Which containers is it compatible with?
A: It fits standard ISO shipping containers with ISO 1161 corner castings, including common 20ft and 40ft dry containers, flat racks, open tops, and tank containers.
Q: How is the twist lock mounted?
A: The square base plate is bolted to the chassis rail, trailer frame, or flat rack structure through its four pre-drilled mounting holes. This bolt-on design allows fast installation with standard tools and easy replacement when needed.
Q: Why is the galvanized finish important?
A: The galvanized zinc coating shields the cast steel body from salt spray, humidity, and cargo sweat that are common in ports and on ocean routes. It extends the service life of the container twist lock and reduces maintenance and replacement frequency for fleet operators.
Q： Can you accept custom‑made twist locks?
A: Yes, we support OEM service. Custom logo, marking or special specifications are available upon request.
Q： What is your delivery time?
A: Standard stock items: 7‑15 working days. Custom orders will depend on your requirements.
