Locking Grommets
These grommets snap into place and have wings that expand against the sides of the hole to lock them in position. Use them to protect wire, cable, and cords by turning 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.

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.

Snap-In Pipe and Tubing Grommets
These grommets have two flanges that snap around holes and flex to compensate for misalignment and movement of pipe and tubing. They're often used for routing applications in panel walls. Made of plastic, these grommets are chemical resistant and won't dry out and become brittle when exposed to UV rays. All have a medium-hard rating to withstand high levels of impact. They can be used outdoors.
