Why it works

Why fit an end cap

Corrosion resistant

Self-coloured aluminium resists rust, so the cap won't corrode where a painted finish might chip.

Neat finish

Domed aluminium cap covers the raw tube edge for a tidy, finished look.

No tools needed

Slides straight over the tube end by hand, no adhesive or fixings required.

Keeps debris out

Seals the open tube end against dust, moisture and insects.

Frequently asked questions

What size tube does this end cap fit?

It's sized for 20mm square tube - the cap slides over the outside of the tube end for a snug fit.

How does it stay in place?

It's a tight slip-fit over the tube's exterior, held by friction - no glue or fixings needed.

What's it made from?

Self-coloured aluminium - left in its natural metal finish rather than painted or plated.

Can it be painted to match the tube?

Yes, though the raw aluminium finish is designed to be used as-is and needs no coating to resist corrosion.

Is it sold individually or in packs?

Sold as a single cap - order one per tube end you need to finish.

Will it fit round tube?

No - this is a square profile cap made specifically for 20mm square tube ends.

How is it different from the plastic end cap?

It's metal rather than plastic, and fits over the outside of the tube rather than pushing into it - a harder-wearing option for exposed or higher-wear ends.
