Container Twist Lock
Manual twist lock for stacking shipping containers. Left-right hand locking design secures containers vertically for safe, stable storage.
Dovetail Twist Lock
Designed to anchor shipping containers to flat surfaces and ground installations. Prevents wind displacement, theft, and shifting by securing containers to concrete, asphalt, or reinforced foundations.
Ground Anchors
Heavy-duty ground anchors designed for stacking and securing shipping containers to concrete foundations or ground surfaces. Provides maximum stability against wind displacement, theft, and shifting in all weather conditions.
Bridge Clamp
Securely connects two shipping containers side-by-side by hooking into corner castings and tightening with industrial-grade hardware. Creates a stable horizontal connection for expanded storage space or multi-container structures.
FAQ
Twist locks are used to stack containers vertically by connecting the top corner castings of one container to the bottom castings of another. Ground anchors (dovetail locks or foundation plates) secure containers to flat surfaces like concrete or asphalt to prevent wind displacement and theft. Use twist locks for stacking; use ground anchors for permanent single-container installations.
You need four twist locks—one at each corner where the containers meet. Never use fewer than four locks, as this creates uneven weight distribution and serious safety hazards. All four corner castings must be locked to ensure stability against wind, seismic activity, and load shifts.
Yes, manual twist locks and ground anchors are designed for DIY installation with basic tools. For ground anchors, you’ll need to drill into concrete and use appropriate bolts. For stacking twist locks, ensure both containers are level and all four locks rotate fully (90 degrees) to engage properly. Always follow manufacturer installation instructions and local building codes.
Ground anchors aren’t required for all single containers but are highly recommended in certain situations: high-wind areas (coastal regions, tornado zones), sloped sites where containers may shift, open yards with theft concerns, or when local building codes require anchoring for permanent structures. Anchors provide peace of mind and protect your investment.
