This seal operates on the same principle as the Roto-Seal®, but requires no sealing tool. Made from durable acrylic plastic, this seal has a transparent body and a colored insert. It is available with or without a pre-installed stainless steel wire. The Toolless Roto-Seal® features a large flag, which is heat stamped with company name or logo and consecutively numbered. Laser etched bar coding available in Interleaved 2 of 5, Code 39 or Code 128. For added security, the last three digits of the seal number are laser etched onto the insert.
