EngVan truck, container rear door locks – latches
Van rear door locks are specialised locking mechanisms designed for the rigid fixation of door leaves on commercial vehicles. Conceptually, they consist of handles, bars (rods), cams, and keepers that hold the doors securely in a closed position. They ensure the airtightness of the cargo compartment and protect its contents from unauthorised access. Furthermore, they are designed to prevent accidental door opening during transit and guarantee a tight seal against door gaskets, which is critically important for isothermal vans and refrigerated units.
Types of Rear Door Locks for Vans
External locking devices for transport are classified based on the body construction, the weight of the door leaves, and the vehicle's operating conditions. For large-scale commercial transport, the following solutions are most in demand.
- Cam-Action Bolt Locks for Van Rear Doors and Gates. This is the most common type of external mechanism. The system consists of a vertical tube (bar) attached to the door and a heavy-duty handle. When the handle is turned, the cams at the ends of the bar engage with keepers on the frame, providing powerful compression. These systems are universal and suitable for both dry freight boxes and shipping containers.
- Recessed Locks for Trucks. Used when it is necessary to maintain a smooth door surface (e.g., for aesthetics or vehicle branding). The mechanism is hidden inside the door panel, which also provides an additional barrier against intruders.
- Over-centre and Toggle Latches. Primarily used on light commercial vehicles and trailers. They are compact, easy to install, and provide quick fixation for dropsides or small rear cargo doors.
- Specialised Container Locks. Distinguished by increased bulk and reinforced cast parts (handles, cams). Since shipping container rear door locks must withstand static loads during multi-tier storage, they are manufactured from high-strength alloys with anti-corrosion coatings.
Technical Specifications to Consider When Choosing Locks for Trucks and Containers
When selecting a product, it is vital to consider not only the price but also compliance with industry standards. Therefore, attention should be paid to the following indicators.
Materials and Protective Coatings
Galvanised or stainless steel are most commonly used.
Galvanised Van Rear Door Locks. The optimal choice for price and quality. The zinc layer protects the metal from corrosion in inclement weather, the influence of road reagents, and extreme temperature fluctuations.
Stainless Steel (AISI 304). The standard choice for refrigerated vehicles and food transporters, where resistance to aggressive cleaning agents and a total absence of rust are essential.
Bar Diameter and Wall Thickness
The strength of the system depends on the tube parameters. Standard sizes include 22 x 1.5 mm or 22 x 2 mm for medium-duty transport, and 27 x 2 mm or 27 x 3 mm for HGVs and heavy trailers. Wholesale procurement must account for the specific fleet requirements: using a bar with insufficient wall thickness on heavy doors will lead to deformation under the weight of the cargo or during vibration.
Vibration Resistance
High-quality rear door and gate locks for vans are equipped with anti-vibration inserts and handle locking mechanisms.
Ergonomics and Security
The presence of holes for customs seals and the ability to fit a padlock to the handle is essential. In modern models, plastic or rubberised handle grips are also valued, as they facilitate the driver's work in winter conditions.

Questions & Answers
- How do I choose the correct lock for the bar (tube) diameter?
The choice depends on the dimensions and weight of the gates. For light trucks and vans, systems for 22 mm tubes are usually used. For HGVs, trailers, and shipping containers, reinforced locks for 27 mm or 34 mm bars are the standard. Before ordering, we recommend measuring the outer diameter of the existing tube or checking the technical requirements of the van manufacturer.
- Is it possible to replace individual lock elements without welding?
Most modern cam-action systems in our catalogue are bolt-on/modular. This means that components such as handles, plastic bushes, and bar brackets are fixed with bolts or rivets. This allows for rapid repairs within the fleet without the need for welding equipment, reducing vehicle downtime.
- Is there an option for sealing or installing additional security measures?
Yes. Most of our handles for van rear doors feature specific holes for customs sealing wires or eyes for padlocks. This allows for additional cargo access control and prevents unauthorised opening during transit.
