The Cralu roll-up seal is versatile, in particular it is used to secure mail and valuables containers, bags and fittings.
Cralu is made of aluminum and is always used in combination with a plastic, copper or galvanized steel wire or a hemp cord (see accessories).
To apply the seal, a piece of wire or cord is threaded into the seal opening. After a simple knot has been made at the desired height for attaching the roll-up seal, the cralu is attached at this point. Coding pliers are required for closing
