Spring-Fast Grommet Edging:  SL Series

The SL Series has a steel substrate fully encapsulated in flexible, lubricious TPE
for superior abrasion and chemical resistance.
It has 4-axis flexibility and acts as a best in class grommet edge or a high performance edge trim.

Key Benefits

  • Superior performance: encapsulated stainless steel core: outperforms plastic grommets.
  • Snap on installation lowers costs 49% vs. grommets with glue.  Watch the 4 min. video below.
  • Improves efficiency 9.5x – due to fewer steps in workflow.

  • Used in high performance applications: aircraft structures/interiors, avionics systems,
    military vehicles, NASCAR vehicles, supercomputers, medical equipment and rail transit
  • Straight, roll formed and flanged edges
  • Multi axis flexibility for flanged holes and small radii inside or outside corners
  • High performance edge trim


The old nylon grommet with glue is old, inefficient and costly.  DTi has a better way.

  • 100% TPE encapsulated stainless steel substrate
  • Snaps on fast with finger pressure
  • Installs continuously with multi axis conformity
  • Self locking with strong retention with no adhesives
  • Simpler install: no adhesive, fixturing, curing, clean up or OSHA concerns
  • Maintenance is far easier due to its ease of application, use and removal
  • Customization available (lengths, colors and print)
