The Story
The black powder coated square staircase spindle measures 1118mm in length with a 13mm square section, making it a practical choice for contemporary staircases where a clean, geometric aesthetic is required. Manufactured from mild steel hollow section with a durable matt black powder coat, it fits directly into 13mm groove handrail and base rail systems.

What it's used for
- New staircase installations requiring a modern, square-profile metal balustrade system
- Replacement of worn or damaged spindles in existing 13mm groove rail staircases
- Feature stairs in residential hallways, landings, and mezzanine levels where a matt black finish suits the interior scheme
- Loft conversions and new-build staircases specified with steel balustrade components alongside timber handrails and base rails
Fitting and handling
These steel spindles slot into pre-routed 13mm grooves in both the handrail above and the base rail below, so check your groove dimensions carefully before ordering. Space spindles at a maximum of 99mm apart (measured between spindle faces) to comply with current UK Building Regulations, which require gaps to be no greater than 100mm. Store spindles flat and off the ground prior to installation to avoid any distortion to the powder coat finish.
FAQ
Will this spindle fit my existing handrail and base rail?
This spindle is designed for use with rails that have a 13mm routed groove. If your existing rail has a different groove size, such as 41mm or a round-section groove, this spindle will not be compatible. Measure your groove width before ordering.
Is the powder coat finish durable enough for a busy family staircase?
Powder coating provides a harder, more chip-resistant surface than wet paint, making it well suited to interior staircase use. Avoid abrasive cleaning products, which can dull the finish over time. A wipe down with a damp cloth is all that is normally needed.
How many spindles do I need for a staircase?
As a general guide, most staircases require two spindles per tread, though this depends on your tread width and the spacing required by Building Regulations. Measure your total balustrade run and divide by the maximum permitted 99mm spacing to calculate the minimum number required, then round up.
