Maximum-security container door locking inside Twistlock Africa weld-on lockboxes; high-risk storage and transit.
A one-piece forged brass body carries case-hardened, tempered and chrome-plated steel main armour (2.5 mm or 3 mm depending on model) with side armour from 1 mm to 1.5 mm. The case-hardened rotating dead-bolt resists attack, and the 7-pin plug defeats drilling and picking. Sized to drop into the weld-on lockboxes on the preceding page.
