PRODUCT OVERVIEW
MC-K2 overview
Quick answer
MC-K2 is a single-use, pull-tight cable seal for container, truck and door closures where you want to pull the loop snug against the hasp. The cable is 1.8 mm (0.07 in) braided aircraft cable with a 300 mm (11.8 in) standard length, and custom lengths are available. The hexagonal lock head is extruded zinc wrapped in ABS and is described as petroleum and sunlight resistant. Feed the cable through the closure and through the head, then pull it tight; it cannot be loosened. The catalogue lists an average tensile strength above 250 kgf. Remove with bolt or cable cutters. MOQ is 1,000 pieces, 1,000 per carton.
How it locks
The cable passes one way through the locking mechanism in the head. Pulling shortens the loop; any attempt to pull it back is blocked, so the seal must be cut to open.
Not suitable when
- you need a seal that removes without tools;
- the closure holes are smaller than the 1.8 mm cable;
- your buyer requires a documented security classification – request model-specific test evidence first.
Compared with similar models
- MC-K – same 1.8 mm cable but a fixed-length lock, 230 mm standard length and 150 kg catalogue tensile.
- MC-NCF / MC-CF – pull-through cable seals with aluminum bodies and a choice of 1.0–5.0 mm cable diameters.
- MC-BS02 bolt seal – rigid 8 mm pin for standard container hasps.

APPLICATION CHECK
Where to use MC-K2
Catalogue-listed uses: ISO containers, trucks and doors. The pull-tight lock suits closures where the gap between holes varies: truck rear doors, swing-door handles, tanker valves and cargo hatches. Pull the cable snug so the loop cannot slip over the handle. The image is a catalogue product photo and does not establish a transport security classification.
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.
