Plastic Edging – Grommet Edging

The traditional names for these products vary, but to name a few:  plastic grommets, plastic edge protection, flexible edging, rubber edging trim, rubber edge trim, wire grommets, caterpillar grommets, railroad track grommets, chicken track grommets, cable bushings, cable pass-throughs and cable grommets.

Cables or wires passing through or over sheet metal, rigid plastic or composite frames can suffer abrasion from sharp edges. This can break down the electrical insulation and cause a range of problems from data loss or complete lack of functionality to arcing and possibly catastrophic fires.

Traditionally, simple molded plastic edging grommets have been used to prevent this.  The most common is the old MS21266 and/or BACG20Z in Nylon or PTFE. These have no retentive strength unto themselves with installation procedures requiring an adhesive application which is labor intensive, costly in time and has safety issues (VOC’s) due to the solvents and glues.  Further, over time, the glue and nylon grommet will degrade, become embrittled and fall out.  The Spring-Fast family of grommet edging outperforms the traditional nylon grommet strips and does it at a lower installed cost in a fraction of the time.
