3 m-on-6 m and 3 m-on-12 m container stacking; load distribution across the lower container; securing against lateral movement in wind.
Placed between a short container and the longer one beneath it, the spacer spreads the load and stops the upper container shifting in adverse weather. It secures to the bottom corner casting through a purpose-designed internal locking mechanism. Supplied in Twistlock Africa blue (any colour on request); lead time roughly 2 weeks. Compatible with all ISO 1161 corner castings on standard 20 ft and 40 ft containers.

◇ Technical drawing — included in the datasheet above.
Manual double-ended twistlock — the industry-standard connector that locks ISO container corner castings together for safe vertical stacking, with a hand-thrown lever and clear locked/unlocked indication.
Semi-automatic double-ended twistlock — engages automatically as one container lands on another; pull the toggle to lock it open for the next lift, giving crane crews an at-a-glance 'ready to lift' signal.
Fully automatic twistlock — locks itself when containers are stacked and releases on lift, removing manual handling from routine cycles for the highest-throughput terminal operations.
Bridge clamp — locks the top corner castings of two side-by-side containers together horizontally, turning a row of containers into a single braced wall when used with twistlocks.
