PRODUCT OVERVIEW
MC-CFB overview
Quick answer
MC-CFB is the thicker-cable version of MC-CF: a single-use, pull-through cable seal with an aluminum body and aeronautic steel wire rope in 3.0, 3.5, 4.0 or 5.0 mm (0.12–0.20 in). The cable length is made to order. Pass the cable through the closure and the body, then pull it to size; it locks one way and cannot be loosened. The locking device is zinc-alloy die-cast and the construction contains no plastic. Marking is laser only and appears white. MOQ is 1,000 pieces, 1,000 per carton; remove with a heavy cable cutter.
How it locks
The cable and locking mechanism grip and press the cable together as it is pulled, so the loop can only get shorter.
Not suitable when
- the closure holes are smaller than the chosen cable diameter;
- you need colored printing – white laser marking only;
- only light hand tools are available for removal – 4.0–5.0 mm cable needs a heavy-duty cutter;
- you need a published break-strength value – the catalogue does not state one.
Compared with similar models
- MC-CF – same design with 1.0–2.5 mm cable for lighter closures.
- MC-NCF – adjustable cable seal covering 1.5–5.0 mm in eight diameters.
- MC-BS02 bolt seal – rigid 8 mm pin for standard container hasps.

DIMENSION REFERENCE
MC-CFB dimensions
Check the original dimension drawing and your closure openings before ordering.
APPLICATION CHECK
Where to use MC-CFB
Catalogue-listed uses: ISO containers, trucks, bank and logistics doors. The thicker cables suit container door handles, rail wagon latches, tanker manifolds and heavy equipment covers where a thin cable would look or feel inadequate. Images are catalogue product photos and do 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.

↓BUYING QUESTIONS
MC-CFB FAQs
Which diameters are available for MC-CFB?
3.0, 3.5, 4.0 and 5.0 mm. For thinner cable, choose MC-CF (1.0–2.5 mm).
How do I choose between 3 mm and 5 mm?
Start with the smallest closure hole – the cable must pass through freely. Thicker cable is harder to cut and suits heavy closures; thinner cable is easier to install.
What break strength does MC-CFB have?
The catalogue does not state a tensile value. Request model-specific test evidence for the selected diameter if you need a defined strength.
Can the body be printed in color?
No. The aluminum body takes white laser marking only.
What is the minimum order?
1,000 pieces, packed 1,000 per carton.
