FAQ's

What size tube does it fit?
The standard elbow (128-4) fits 48.3mm scaffold tube. It’s also available for 42.4mm, 33.7mm and 26.9mm tube — select your size at the top of the page.
Is it suitable for outdoor use?
Yes. It’s blackheart iron, double galvanised for corrosion resistance, so it holds up outdoors.
What’s it commonly used for?
Top corners of square structures, benches, market stalls, display stands, tables and similar frames. It’s often paired with the 116-4 handrail fitting.
Do you keep these in stock?
They’re ordered direct from our supplier, so allow 2–7 working days.
