TC770 is used to attached handrail onto wall structure at any angle. Install the TC770 bracket onto wall using 3 x M6 concrete fasteners or 14-gauge timber screw. While the railing pipe (B34 25NB / C42 32NB / D48 40NB) could be secured using galvanised hex course self-drilling screw 12-14 x 25mm. Rivets or self-drilling screws can be supplied separately at extra cost.

Although TC770 saddles type Assist fittings are primarily designed to fit snugly on C42 diameter tubes, they may also accommodate B34 & D48 tubes with a slight central gap when fitted.

This fitting can be mounted to the wall at any angle which makes it a very versatile fitting for walled ramps and stairs. The smooth finish of the fitting complies with Australian Standards for smooth finished top handrails.

- The TC746 is a shorter variant to the 770

Product FAQ

Which fitting size do I chose?

We offer fittings in various sizes that meet Australian standards, ranging from 21mm to 60mm. 

To select the right fitting, measure the outside diameter (OD) of your pipe and choose the corresponding size. For example, a pipe with a 48mm OD requires a D48 fitting. 

We also provide fittings for 50mm aluminium tubes and 25 x 25 or 40 x 40mm square hollow section steel bar.

Metric or Imperial?

You'll see a table that compares various international measurements in the 'Size Guide' section above.

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.
