Cover Plugs TP30 in the black version are a ribbed tube end plug for round tube, made in polyethylene (PE) with a matte surface. The plug closes open tube ends in frames, machine stands, railings and furniture tube; a small component that lifts the overall impression and solves several practical problems into the bargain.

The series covers 10 sizes for round tube, from 10 mm up to 140 mm in tube outer diameter. Each size is made for a range of wall thicknesses; across the series as a whole that means roughly 0.5 to 7.0 mm. Check the actual dimensions of the tube against the table in the manufacturer's data sheet before you order; nominal tube dimensions can differ a little between tube manufacturers, and it is the actual dimension that decides how well the plug sits.

The range is unusual: besides slim tube around 10 to 20 mm there are plugs for heavy tube of 100 to 140 mm, sizes that can otherwise be hard to get hold of. Delivery is in packs of 25 to 2000 pieces depending on size. A rubber mallet helps when fitting the larger sizes. Do not strike the plug directly with a steel hammer; the head then risks being deformed and the seal gets worse. Plugs that have sat out in sun and weather for several years can become more brittle, so replace them along with other maintenance if they start to look tired.
