HTF has been leading the way in hardware and component distribution for 30 years. Over the years HTF has continued to foster strong and long-lasting partnerships with industry leading part manufacturers. Delivering same-day shipping and a vast catalogue of fasteners and components is key to the success of HTF and would not be possible without the teamwork of over 25 manufacturing partners. Each year the inventory grows as partners are added and innovative new parts become available. One such trusted partner to HTF is Device Technologies, Inc. (DTI). 

DTI, like HTF, has been in business for 30+ years. To be exact, DTI began 37 years ago in 1984 from modest beginnings in an old farmhouse basement. Fast forward to today, DTI has grown substantially to a state-of-the-art, climate-controlled class A facility. Their success as the original source for wire protection grommet edging has been on an upward trajectory since their start thanks to consistently meeting their customer’s needs under an AS9100 Quality Control system. 

Wire Protection Grommet Systems

The DTI line of wire protection grommet systems are proven to cut costs by 49% thanks to their superior performance. The encapsulated spring steel core of the grommet system outperforms plastic grommets every time. Another attribute that cuts cost in half is the time saved with snap-on installation compared to glue. With fewer steps in the workflow, efficiency of the snap-on grommets is 9.5 times faster. There are 12 types of Spring-Fast grommet edging from high-heat to military applications and more. 


  • Snap-on install lowers costs by 49% vs. grommets with glue.
  • Improves efficiency 9.5x due to fewer steps in workflow.
  • Nylon clad substrate assures high performance in normal or hostile environments.
  • Flame retardant per UL94V-0
  • Vibration compliant to Telcordia GR63-CORE

Enclosure and Door Seals

The DTI line of enclosure and door seals help to protect against environmental conditions such as dust, fumes, heat/cold, and moisture. The Seal-Fast Edge Seal and Seal-Fast Plate Seal create effective solutions for sealing your data services and equipment quickly and efficiently.

Seal-Fast Edge Seal

  • Seal-Fast seals offer the best way to provide environmental protection from dust and moisture — even M&M’s™ and French fries (an actual automotive requirement!).
  • 100’s of COTS (Commercial Off the Shelf) options available in PVC/EPDM, EPDM, Silicone with or without steel or stainless-steel substrate. Snaps on easily with strong edge retention.

Seal-Fast Plate Seal

  • A fast and reliable way to protect critical equipment in places where wire, cable, air hoses, fuel and oil lines pass through fire walls, bulkheads, wall panels and enclosure openings and avoid contact with sharp panel surfaces while also sealing the aperture for airflow, heat loss and or insect/rodent penetration.

Fiber and Cable Management

There are many benefits to having proper fiber and cable management including faster rewiring, ensuring data flow, and expediting troubleshooting. These benefits also reduce time and costs by simplifying the work.
