The principle of cable seal is to lock the seal through the countersunk lock body and internal steel balls, springs and other parts to prevent it from being illegally opened or copied. This kind of seal belongs to disposable consumables. Once it is sealed, it cannot be opened without damage unless it is cut by a tool, thus ensuring its anti-theft and anti-counterfeiting effects. The use conditions of steel wire seal include its size limit, and the general steel wire diameter, exposed length and whole length are specified in detail to ensure that the sealed articles are suitable in size and easy to operate and manage.

The function of this cable seal crank is to play the role of double insurance. After the steel wire passes through, it is locked, and then the crank is tightened. After tightening, the exposed crank can be broken. If the tension required by the customer is relatively large, you can choose this steel wire seal.
