Close off unused holes to block dust, debris, and moisture from entering machine panels. These plugs also cover sharp edges in sheet metal to prevent cuts. They secure with flexible prongs or a ring, so you can quickly install and remove by hand.

Polyethylene—A balance of wear and chemical resistance for use in a variety of environments. These plugs withstand scratches and scrapes as well as mild acids, solvents, and chemical cleaners.

Nylon—Durable and wear resistant, these plugs also resist oils, solvents, and mild acids.

Snap-In Rectangular Plugs

For a tighter fit than push-in plugs, these have flexible ribs that grip a range of rectangular tubing sizes. They are good for semi-permanent installations, such as finishing the ends of posts, workstations, and furniture. To remove, you’ll need a tool such as a flat-head screwdriver to pop them out.

Polyethylene—A balance of wear and chemical resistance for use in a variety of environments. These plugs withstand scratches and scrapes as well as mild acids, solvents, and chemical cleaners.

Locking Panel Plugs

Nylon

Shaking and rattling won’t dislodge these plugs. They have tabs that compress when pushed into the hole and then pop out on the other side to lock in place. These are the most secure panel plugs—you’ll need a tool such as a screwdriver to remove them.

Nylon—Durable and wear resistant, these plugs also resist oils, solvents, and mild acids.
