.75 (3/4) Inch HD Serrated Seal
.75" HD Serrated Seal- Poly Strapping Seals. The 3/4" Heavy Duty Serrated Seal is for Polyester (PET) Strapping. The serrations grip the poly strapping and give a much better joint efficiency than the standard poly seal. There are 1,000 per box model. This seal is used with the 381 poly sealer.
Allstrap Opinion:
These seals are the ONLY serrated seals that we have tested that meet the ASTM standards. If you are using a 3/4" serrated seal for poly, it should be these. If you use lots of seals, then you should consider a battery powered tool that welds the strap. The weld is free, and stronger than a clip. Check out the Xtreme, P329, or BXT3-19 battery guns. This seal works with the long handle sealers, and we like this for manual sealing applications.
