Lock rod isolator
Quench-hardened lock rod isolator — the industry-standard removable device for securing liner-owned containers in transit; adjusts to different container configurations and takes a replaceable UNION lock, keyed-alike on request.

Loose, slip-on steel lock box that sleeves over the container door handle and encloses the padlock shackle. No welding, no drilling: fits hired and customer-owned containers and moves with you.

Where the weld-on lock box (TLA-SEC-LBOX-01) is fixed permanently to the doors, the loose lock box slides over the vertical lock rod handle and is secured through the box with a padlock, so it can be fitted in seconds and removed without a trace. The enclosed shroud keeps the shackle out of reach of bolt cutters and pry bars and shields the padlock from weather. Fabricated locally by Twistlock Africa from 4 mm S355JR plate, continuously welded and professionally powder-coated in Twistlock blue. Fits the standard ISO lock rod handle, either door. Supplied box-only (TLA-SEC-LBXL-01) or as a kit with padlock (TLA-SEC-LBXL-KIT); keyed-alike sets on request. Fit one per lock rod handle; two per door set where both handles are to be secured.
