Specifications
| Attribute | Detail |
|---|---|
| Material | Softwood |
| Treatment | Pressure treated |
| Nominal Size | 35mm x 35mm |
| Length | 900mm |
| Profile | Round detail spindle |
What it's used for
- Staircase balustrades between handrail and base rail or string
- Landing balustrade infill panels in residential properties
- Garden decking balustrade rails where a decorative turned profile is required
- Replacement spindles for existing staircases where the original section has been damaged
Fitting and handling
Before fitting internally, allow the spindles to acclimatise in the room for at least 48 hours to reduce the risk of movement after installation. Fix into a routed base rail or use proprietary spindle connectors, ensuring equal spacing to comply with current UK building regulations, which require gaps of no more than 100mm to prevent a 100mm sphere from passing through. For external applications, ensure any cut ends are treated with an end-grain preservative before installation.
FAQ
What is the finished diameter of the round section on this spindle?
The nominal section is 35mm x 35mm. The turned round profile will be slightly under this dimension once machined, which is standard for softwood spindles of this type. If you need a precise finished diameter for a specific fitting, please contact Nottage Timber Merchants before ordering.
Can these spindles be used outdoors on a decking balustrade?
Yes. Because they are pressure treated, these spindles have improved resistance to moisture and fungal decay compared with untreated timber, making them suitable for sheltered exterior use such as decking balustrades. We recommend applying a suitable exterior timber finish after installation and re-coating periodically.
How many spindles do I need for a standard staircase?
The number required depends on your staircase width, rise, and the chosen spacing. As a guide, UK building regulations require a maximum 100mm gap between spindles. Measure your total run, divide by roughly 100-120mm per spindle, and add a small allowance. The Nottage Timber Merchants team are happy to help you calculate quantities.
These treated softwood round spindles are stocked alongside our full range of base rails and handrail components to help you complete your balustrade project in one order. Nottage Timber Merchants offers convenient collection from Bridgend and local delivery across South Wales.
