Zip Tight Bag Seals
Zip Tight Seals (N-LOK)
Zip Tight Seals Zip Tight adjustable bag seals are medium strength pull-tight seals designed to be used on bags or any other equipment requiring a highly tamper-resistant locking mechanism with a reasonable degree of strength.

Zip Tight seals are commonly used as fire extinguisher seals or fire extinguisher tamper seals that fix around the safety pin to deter tampering or vandalism. Their low breaking strength allows for manual removal in the event of a fire emergency. Nelco's fire extinguisher seals can be custom printed with your design or logo.

Zip Tight Seals are:
  • Durable, all plastic, one-piece construction.
  • Patented, tamper-resistant nylon locking mechanism.
  • Thin, yet strong sealing strap designed to fit most locking rings and equipment latches.
  • Individually numbered or barcoded and stamped with company name and logo for easy identification.
