Let’s take a deeper look at one of those systems.

Grommet systems are used across a range of industries and in a variety of environments from the average office to military and aerospace. The grommet’s easy application protects exposed edging reinforcing the material surrounding it, providing a more protective space for wires and cables.


Simply put, a grommet system is a ring or eyelet that has been inserted into an access hole for the purpose of providing a protective edging for rough edges, using a thin  material. Regardless of what the manufactured product’s material is–plastic, wood, or metal—there are always rough edges or burns where the access hole was cut.  The grommet edging can be directly applied to the surface material, equipping components such as wires from harm. These systems can be pre-cut and customized to  the length requirements necessary for your chosen material.

How does grommet edging work?

The main function of the grommet is to reinforce the material surrounding them, allowing wires and cables to pass through easily without the potential for damage. This edging is important, because damage to wires and cables from sharp or rough-edged material increases the possibility for failure to electronic and communication equipment, in addition to health and safety hazards such as electric shock or fire.


Device Technologies, Inc., (DTI), has been the original source wire protection grommet edging for over 30 years, and its success has been on an upward trajectory since their start thanks to consistently meeting their customer’s needs under an AS9100 Quality Control system. HTF is proud to partner with them to offer solutions for all of your wire protection grommet system needs.

Spring-Fast Grommet Edging

DTI has a line of wire protection grommet systems that are proven to cut costs by 49% due to their superior performance. The encapsulated spring steel core of the  grommet system outperforms plastic grommets every time. Snap-on installation cuts costs in half, when compared to grommet systems using glue during install, and  creates a 9.5 times more efficient workflow. Spring-fast grommet edging has 12 types with functions ranging from high-heat to military application among many others.

Enclosure and Door Seals

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

Fiber and Cable Management

In addition to faster rewiring, ensuring data flow, and expediting troubleshooting, proper fiber and cable management simplifies the work, reducing time and costs associated with installation.


Made from a variety of materials including, silicone, rubber, polyethylene, PVC, and encapsulated metal strips, grommet edging provides strength and durability with low  surface friction using thermoplastics. Using long-lasting materials like silicone rubber increases retention and reduces the need for adhesive. Nylon or PVC provide a cost- effective grommet system without compromising component protection. However, nylon requires adhesive, reducing the lifespan of the material. Finally, encapsulated  spring metal offers the best solution for most applications to protect wires from wear and damage.

Define the Overall Purpose

When choosing grommets, understanding the purpose of the selection is essential. What will you be protecting? What material are you installing the grommet into?  Ranging from desks to industrial applications, grommets have a variety of materials and sizing to match their overall function.

Think About the Look of the Selection

With the overall purpose of the grommet defined, let’s look at the product you are installing a grommet into. If it has a more functional and utilitarian role, black plastic  or rubber grommets are a great choice. Finishes like polished metal grommets and grommets with covers that can be snapped into place, after the wires have been run  through are for higher end needs. Polished grommets are mostly circular in nature, but rectangular options are available as well as grommet strips for straight edges.

Consider the Sizing

When determining the size of the grommet, consider the size of the opening as well as the thickness of the wires and cables you intend on running through the access  hole. The number of wires you aim to run through the grommet is beneficial knowledge, because it helps determine the necessary diameter of the grommet.

Grommet Edging Materials

Depending on the application, there are many different grommet edging materials available with a range of price points and benefits.

  • SILICONE RUBBER is a synthetic polymer also known as polydimethylsiloxane. This tough material has superior durability and flexibility, making it an ideal solution for grommet edging. Silicone rubber resists corrosion and most chemicals, and has many functionalities including being a good insulator, with the ability to handle high temperatures. This material is smooth in nature, reducing friction and the risk of wear or damage to wires and cables. Most often this material is used as a grommet strip edge, protecting along straight runs due to its rigidity.

  • PVC, or polyvinyl chloride, is a naturally rigid synthetic thermoplastic. As a grommet edge, PVC requires plasticizers to be added to improve its workability, and make its flexibility consistent with the metal core. Combining the PVC with an aluminum core provides the ideal retention for installation without adhesives. The material’s strength and affordability offer a cost-effective substitute for silicone rubber.

  • NYLON, is another synthetic thermoplastic, providing strong corrosion, chemical, and abrasion resistant grommet edging protection. The material has low surface friction, protecting cables from breaking down over time, but requires adhesive to be applied during installation, which reduces the lifespan of the material.

  • ENCAPSULATED METAL GROMMETS have spring stainless steel encapsulated with durable flame retardant thermoplastic. This material does not require adhesive, offering comparable strong edge retention to others mentioned above. This extends the durability of the grommet system and lowers the cost for installation.
