What are they?

A box containing the 12 L shaped bars, clamps and fixings needed to form a set of riser bars for the Optima spiral stair.

What do they 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 do they fit?

The short ends of the L shaped bars are fixed on top of each tread near the centre column. The long end is then clamped to the baluster which connects the tread to the one above. Riser bars can be fitted to the stair after it has been fully installed although it is easier to do so during the main assembly.

What do I get in each kit?

Each kit contains twelve L shaped riser bars and the necessary fixings for the Optima spiral stair.

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 riser bar kits for the main stair kit and extra singular riser bars if you have ordered any extra tread kits.
