PRODUCT OVERVIEW
MC-WS01 overview
Quick answer
MC-WS01 is a single-use twist meter seal for water, gas, electric and electronic meters, tanker valves and pipe equipment. The body is clear polycarbonate so inspectors can see the wire inside, and the wire is 0.7 mm (0.03 in) galvanized or stainless steel with a 20 cm standard length. The wire can be supplied loose or pre-attached. Pass the wire through the two holes in the body, turn the handle to the right to wind it tight, then break the handle off to lock. Remove with cable cutters. MOQ is 1,000 pieces, packed 5,000 per carton.
How it locks
Turning the rotor winds the wire inside the body; breaking off the handle leaves no way to unwind it, so cutting the wire is the only way to open the meter.
Not suitable when
- you need a seal for container or truck doors – choose a cable or bolt seal;
- the meter holes are smaller than the 0.7 mm wire;
- your order is very small – samples are available, but MOQ is 1,000.
