PRODUCT OVERVIEW
MC-DH-V overview
Quick answer
MC-DH-V is a single-use, heavy-duty barrier seal that locks across the two vertical door bars of a container, truck, van or rail car, so neither door can be opened. The body is all steel – 361 mm (14.2 in) long, 45 mm wide and 6 mm thick – with five locking-hole positions to suit different spacings between door bars. The lock pin is galvanized low-carbon steel and the seal cover is aluminum. Fit the two barriers around the door bars, then knock the pin into the lock cap. The catalogue lists a breaking force above 3.5 tonnes. Removal needs an electric cutting tool (eye protection required). MOQ is only 10 pieces.
How it locks
The two steel barriers are joined around the door bars and secured by the pin driven into the lock cap; it can only be removed by cutting through the steel.
Not suitable when
- you only need a numbered seal on the door hasp – a bolt seal such as MC-BS02 is lighter and cheaper;
- no electric cutting tool is available at destination;
- the door bar spacing falls outside the five hole positions – send the spacing for confirmation.
Compared with similar models
- MC-BS02 bolt seal – 8 mm pin through the door hasp, removed with bolt cutters.
- MC-CFB cable seal – 3.0–5.0 mm steel cable for heavy closures.

APPLICATION CHECK
Where to use MC-DH-V
Catalogue-listed uses: containers, trucks, doors, vans and rail cars. Barrier seals are used with a standard bolt seal for higher-value cargo: they physically block the door bars so the door cannot be swung open even if the handle is tampered with. Measure the distance between door bars before ordering.
Thread through the zipper pull and adjacent anchor eyelet, then lock and record the identifier. Check both openings, loop clearance and seal engagement on a sample.

It has five locking-hole positions for different door-bar spacings. Send us the distance between the bars to confirm.
How strong is it?
The catalogue lists a breaking force above 3.5 tonnes. No test method is stated; request test evidence if you need a defined rating.
How is it removed?
With an electric cutting tool such as an angle grinder. Wear eye protection.
