Details

The TC251 Stair Base Flange fitting is designed to suit stair rails where it would normally slope from 45-60 degrees. This fitting should only be subjected to light load as it cannot be positioned at 90 degree to the applied load.

Designed for both indoor and outdoor projects, it features our easy slip-on and tighten connection system which only requires a hex key to secure.

Frequently Asked Questions

Which fitting size do i chose?

We offer fittings in six different sizes according to Australian standard pipe sizes, ranging from 21mm to 60mm. To select the right fitting, simply measure the outside diameter (OD) of your pipe and choose the corresponding fitting size.

For example, if your pipe has a 48mm outside diameter, you would select the D48 fitting size.

Metric or Imperial?

You'll see a table that compares various international measurements in the 'Size Guide' section below the product details at the top of this page.

Why is the fitting bigger then my tube?

Our fittings are intentionally made slightly larger than the pipes they correspond to, so that they can easily slide onto both straight and bent bars. If you're worried that the gap might be too big, you can try replacing the grubscrews/setscrews with longer ones.

What are your fittings made from?

Our Tubeclamp fittings are made from Galvanised Steel. Alternatively you can check out of range of Aluminium fittings, or consider having your fittings powder coated.

Where can i find size specifications for each fitting?

You can easily locate size diagrams for most fittings in the example images provided for each product. These diagrams provide approximate measurements for each fitting size.
