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.
