Expansion Rv plugs seal cross-drilled construction
holes. Installation is easy with pneumatically powered
rivet gun that pulls a tapered mandrel through a sleeve
to create an expansion seal. Standard and long mandrel
varieties come in metric sizes from 4 to 10 mm. Sleeves
come in carbon steel and black oxide; mandrel comes in
corrosion-resistant lubricated carbon steel.
