About Durometer Hardness Scales

Expandable Locking Grommets
The center hole has flaps that flex to hold and protect various sizes of wire, cable, and cords while keeping out dust and debris. Snap these grommets into place and their wings expand against the sides of the hole to lock them in position. Use them to turn rough-edged and uneven holes into smooth holes. Made of plastic, these grommets are chemical resistant, and all have an extra-hard rating to withstand high levels of impact.
Grommets that can be used outdoors won't dry out and become brittle when exposed to UV rays.
