Cover Plugs TP22 in the black version are a ribbed tube end plug for heavy rectangular 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 four sizes for heavy rectangular tube, from 50x30 mm up to 120x80 mm. Each size is made for a range of wall thicknesses; across the series as a whole that means roughly 2.6 to 8.0 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.

TP22 is sized for rectangular tube with wall thicknesses of up to 8 mm, profiles that carry heavier frames and frame structures. Delivery is in packs of 50 to 200 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.
