Single Twist Stair Spindle, 12.5mm Square Hollow, 1117mm, Black Powder Coated Metal Baluster

A single twist metal stair spindle in 12.5mm square hollow bar, 1117mm (44in) long, powder coated black: one twisted section part way along the bar. It replaces timber spindles on an indoor staircase or landing for a modern iron look, and is cut to the rake at each end on site. The price shown is for one spindle, with a minimum order of 10.

Why choose this spindle

One simple twist. A single 160mm twist breaks up a plain square bar without making the staircase busy. Set at the same height on every spindle, the twists read as a neat band up the flight.

Finished in black. Powder coated at the factory, so there is no painting to do once the spindles are fitted.

Light hollow bar. 12.5mm square hollow bar, 0.4 kg each, easy to cut with a hacksaw or metal cutting blade.

1117mm long. Long enough for most domestic stairs and landings, with plain ends to cut to the rake top and bottom.

Mix and match. Use it on its own or alternate it with plain spindles from the same range for a pattern.

Where it is used

On indoor staircases and landings, as a straight swap for timber spindles between the handrail and the base rail or treads. It suits new stairs and stair makeovers in houses, flats, offices and shops. These spindles are not recommended for outdoor use.

Specifications

Part lengths are approximate. The overall length can vary by a few millimetres, which makes no difference once the ends are cut to the rake.

How many do you need?

UK building regulations require gaps of less than 100mm between spindles, so most stairs need two spindles per tread. Count the treads, double it, and add the landing length divided by about 110mm.

Is this the right spindle?

If you like the twist but want more of it, the double twist spindle carries two. For no pattern at all, use the plain round spindle. The single twist is also a good partner for plain bars when you are alternating two designs.

Fitting and care

Measure the rake of your stair, then cut each spindle so it sits between the underside of the handrail and the base rail or tread, keeping the pattern at the same height along the flight. Fix the ends with spindle shoes, a grub screw or a metal-to-wood adhesive, keeping each spindle plumb.

The powder coat is the finish. Touch up cut ends with black metal paint. Wipe clean with a damp cloth; do not use abrasive cleaners.
