CARPET SEAL/LOCK
 

This seal is widely used in the carpet industry, all across India by the Carpet/Rug manufacturers. This seal is the identification of the manufacturer.

The wire used in the seals is 1mm pure spring steel,unbreakable wire. The wire is pushed into the seal from both the sides(but 1 side of wire is free to be pushed out). To permanently lock the seal push the free side of the wire(after hooking it to the finished carpet) with a little pressure so that the wire goes in deep enough that it does not come out on pulling(this procedure can be done on the other side of the wire also, to ensure the proper grip of the wire inside the seal.In order to remove a seal or unlock, the only way out is to CUT the wire of the seal with a cutting-plier and that seal can never be used again and this feature is specially useful to avoid any tampering or design theft during or post shipment.

These seals are very handy and useful in day to day use of the manufacturer/buyer because the name and logo of the manufacturer/buyer is a permanent identification of the carpet/rug. The name /logo which is printed on each seal shall be rendered by you, through Fax/Post. Regarding the serial numbers engraving on each seal(it's normally running serial numbers on each individual seal, e.g.1001,1002,1003..so on and so forth.) is specially useful on each seal in order to maintain an absolute and permanent Inventory Control System. This completes the entire configuration of the carpet/rug seal.
