AIA NASM22529

Plastic and composite grommets covered by this specification are intended to protect from abrasion electrical current carrying wire and cable bundles that are routed through metal structures. The grommets are for use in locations where the ambient temperature does not exceed temperatures shown in Table VI or in areas where there is risk of adhesive failure or embrittlement of grommets. The grommets are intended for edge dressing, odd shape holes and circular holes.

This specification covers three types of edging grommets; a plastic caterpillar style applied with an adhesive, and two spring-style, stainless steel based composite grommets requiring no adhesives. Edging grommets are used to provide abrasion protection of electrical current carrying wires and cable bundles routed through metal structures.
