Spring-Fast® Grommet Edging: High Heat Series
Device Technologies Free Sample Kit

 Spring-Fast Grommet Edging:  High Heat Series

The High Heat Series consists of two un-encapsulated raw stainless steel metal only products.
They provide long term reliability for hostile high temperature environments.
They are low profile, multi axis conformable providing excellent grip strength and allow a low profile edge protection treatment.

The High Heat series are the AP and FM Series with no encapsulation.  The FM variant provides a zero clearance flush mount capability.

Key Benefits

  • Superior performance: 304 stainless steel goes where plastic and other polymeric grommets cannot be used.
  • Fast and easy snap on installation, maintaining low installed cost benefits.
  • At least 49% install cost savings vs. Teflon Grommets and glue.
  • Improves efficiency 9.5x – due to fewer steps in workflow.
  • Superior inherent grip strength from the stainless steel design.
