These insolated plastic grommets provide a barrier between your aluminum posts and stainless steel cables
. Since the two dissimilar metals can react with each other to accelerate corrosion (especially in high salt or chlorine environments), a barrier is necessary to disrupt electrical currents and keep the metals out of contact. These products are advised for anyone interested in increasing their corrosion resistance.
Grommets are sized for CableView© posts and may or may not fit in other types of posts.
