Intermediate wall lock for lorries - clamping boards for securing lorry loads

Clamping boards for lorries, or intermediate wall locks, are an easy-to-use means of mechanically securing loads on tarpaulin-covered vehicles or flatbed vehicles. They are simply hooked into the wooden slats and fixed in place using the clamping lever. They allow the load compartment to be divided into different areas and thus create a secure form of load securing. The clamping boards are tensioned horizontally in the vehicle using a lever. The extendable aluminium clamping boards for trucks are equipped with steel end pieces and are rubberised on both clamping sides. They offer a load capacity of 400daN and provide optimum protection for your load.

The high quality of workmanship is also our top priority with this product. It determines how well the product works in everyday use. The aluminium intermediate wall fasteners from Sandax have a rubberised protective cap on both sides and offer a blocking force of up to 400daN.

Frequently Asked Questions About Cargo Partition Locks and Load Restraint Boards

Below you will find important questions and answers about cargo partition locks, adjustable load restraint boards, cargo retaining boards, and their use for mechanical load securing in trucks, vans, trailers, and box-body vehicles.

What is a cargo partition lock?

A cargo partition lock is a mechanical load restraint device used to secure cargo inside a vehicle. Also referred to as a load restraint board or adjustable cargo retaining board, it is used to block cargo, divide the loading area into sections, and help prevent pallets, cartons, furniture, or other goods from shifting or tipping over during transport.

What are load restraint boards used for in trucks?

Load restraint boards are used in trucks to secure cargo through positive blocking and divide the cargo area into flexible sections. They are particularly useful for partial loads, changing cargo, or frequent loading and unloading because they can be installed and removed quickly.

How does a cargo partition lock work?

A cargo partition lock is adjusted to the required length, positioned between suitable vehicle walls or engaged with existing wooden side slats, and secured using a tensioning lever. The lever mechanism braces the board horizontally across the cargo area, creating a stable barrier against cargo movement.

What are the benefits of cargo partition locks for load securing?

Cargo partition locks are quick to install, adjustable, and can be used without additional tools. They help prevent cargo from shifting, organize the loading area, and reduce the risk of transport damage. They are especially practical for varying interior widths and different package sizes.

What materials are Sandax cargo partition locks made from?

Sandax cargo partition locks are made of aluminium and fitted with steel end pieces. The aluminium construction keeps them lightweight and easy to handle, while the steel ends provide stability and durability for everyday transport operations.

Why do cargo partition locks have rubber-coated ends?

Rubber-coated ends improve grip and help protect vehicle walls, wooden slats, and cargo from damage. The rubber surfaces reduce slipping and help keep the restraint board securely in position.

What is the blocking capacity of Sandax cargo partition locks?

Sandax aluminium cargo partition locks have a blocking capacity of approximately 400 daN. This value indicates the force the restraint device is rated to withstand when blocking cargo. Its suitability must always be assessed in relation to the load, vehicle, mounting points, and overall securing method.

What sizes of cargo partition locks are available?

Sandax offers telescopic cargo partition locks in several adjustment ranges, including 1,220–1,520 mm, 1,500–1,800 mm, and 2,400–2,700 mm. This allows customers to choose a suitable restraint board for different cargo-area widths in trucks, vans, trailers, and other commercial vehicles.

An adjustable cargo partition lock is useful when different vehicles, cargo area widths, or loading conditions need to be accommodated. Its continuously adjustable length makes it particularly practical for freight companies, tradespeople, removals, delivery services, and changing transport operations.

Which vehicles can cargo partition locks be used in?

Cargo partition locks can be used in trucks, vans, Sprinter-type vehicles, box-body vehicles, flatbed vehicles, curtain-sided vehicles, and utility trailers. The cargo area must have suitable support or attachment points, and the lock's adjustment range must match its internal width.

Can cargo partition locks also be used in trailers?

Yes, depending on the trailer design and cargo area, cargo partition locks can also be used in trailers, including utility trailers towed by passenger cars. They can help secure small to medium-sized loads such as boxes, furniture, tools, building materials, and general cargo. It is essential that the device is firmly installed and can provide sufficient clamping and blocking force.

What is the difference between a cargo partition lock and a cargo restraint bar?

Cargo partition locks are usually designed as adjustable boards or planks and are often secured against wooden side slats or suitable side walls. Cargo restraint bars are generally round or rectangular bars which, depending on the design, are braced between walls or fitted into rail systems. Both provide positive load restraint but differ in design, application, and attachment method.

Can a cargo partition lock replace tie-down straps?

A cargo partition lock can supplement or partially replace tie-down straps in some situations when the load is adequately blocked through positive restraint. In many cases, combining partition locks with tie-down straps and anti-slip materials is advisable. The cargo must always be sufficiently secured against movement in all relevant directions.

How do I use a cargo partition lock correctly?

Measure the cargo area before use and adjust the cargo partition lock to the appropriate length. Position it correctly and secure it using the tensioning lever. Then check that the board is firmly seated, cannot slip, and effectively restrains the cargo.

What mistakes should be avoided when using load restraint boards?

Common mistakes include incorrect length adjustment, a lever that is not fully engaged, unsuitable support points, damaged rubber coatings, or insufficient blocking capacity for the load. A restraint board positioned at an angle, left loose, or braced against unstable surfaces cannot reliably secure cargo.

How should I inspect a cargo partition lock before use?

Before each use, check the aluminium profile, steel ends, rubber coatings, and tensioning lever for damage. Deformation, excessive wear, missing rubber, corrosion, or a malfunctioning tensioning mechanism are warning signs. Damaged cargo partition locks should be taken out of service.
