PRODUCT OVERVIEW
MC-G2 overview
Quick answer
MC-G2 is a single-use metal strap seal stamped from galvanized tinplate steel, with stainless steel available. The strap is 211.5 mm (8.3 in) long, 8.5 mm wide and 0.3 mm thick, with a 16 × 12 mm locking head. The tail edges are folded so the strap is safer to handle. Seals are supplied 100 per wire in sequential order, which makes counting and issuing easy. The catalogue lists an average tensile strength of at least 516 N. Pass the tail through the closure and into the head until it locks; remove with cutting tools. MOQ is 1,000 pieces, packed 2,500 per carton.
How it locks
The tail is pushed into the head, where a locking clip grips it; it cannot be pulled back out without destroying the seal.
Not suitable when
- you need a colored seal – metal strap seals come in the natural metal finish;
- the closure holes are smaller than the 8.5 mm strap width;
- your buyer requires a barrier-class seal – choose a bolt seal and request its test documents.
Compared with similar models
