What is it?

A box containing the one steel bar, a clamp and the fixings needed to form a riser bar for the F20 spiral staircase extra tread kit.

What does it do?

Riser bars are horizontal bars that fit between the treads to reduce the open gap to less than 100mm, for the safety of young children.

How does it fit?

A small cup holder is fixed to the side of the centre column between each tread. One end of the horizontal bar goes into the cup holder and the other end is then clamped to the baluster which connects the tread to the one above.

What do I get in each kit?

The box contains a singular riser bar and the necessary fixings.

What do I need to order?

Riser bars are optional. You don't need to buy them to be able to assemble the stair. They are an extra safety feature. If you want riser bars for your stair you need to order one of these extra singular riser bars for each extra tread kit you bought. Only buy these singular riser bars in addition to the main riser bar kit that provides the other 11 riser bars for the main stair kit.
