$1.40The Story
Pine square spindle balusters measuring 41mm x 41mm x 900mm are a standard staircase infill component, used to fill the open sections of a balustrade between the base rail and handrail. Machined from softwood pine, each baluster is consistent in section and length, making installation straightforward.
Specifications
| Property | Detail |
|---|---|
| Material | Softwood pine |
| Profile | Square section |
| Nominal Size | 41mm x 41mm x 900mm |
| Finish | Planed / smooth |
| Treatment | Untreated |
What it's used for
- Staircase balustrade infill between base rail and handrail
- Landing balustrade panels in domestic and commercial properties
- Decking handrail infill as a vertical guard rail component
- Interior mezzanine or gallery balustrade construction
Fitting and handling
Allow the spindles to acclimatise in the room where they will be fitted for at least 48 hours before installation, particularly in centrally heated properties, to minimise any movement after fixing. Spindles are typically secured at the top and bottom using adhesive and a nail or screw through the rail, following the balustrade manufacturer's guidelines for spacing, which in the UK must not allow a 100mm sphere to pass through. Once fixed, prime and paint or apply a stain and varnish to suit your finish, sealing all faces including the cut ends to help resist moisture ingress.
FAQ
What spacing should I use between pine square spindles on a staircase?
UK Building Regulations require that balustrade infill is spaced so that a 100mm diameter sphere cannot pass through any gap. For 41mm square spindles, this typically means a maximum clear gap of around 99mm between each spindle, though always check the specific requirements for your project with your local authority or building control officer.
Can these spindles be used on outdoor decking?
These spindles are untreated softwood pine, so if used outdoors on decking they should be thoroughly primed and painted or treated with an exterior-grade preservative stain before and after installation. For exposed outdoor use, consider a treated timber alternative and ensure all end grain is well sealed.
How many spindles do I need for a typical staircase?
The number required depends on the staircase width and rise, but as a rough guide most standard UK staircases use two spindles per tread step. Measure your total balustrade run and divide by the combined spindle width plus gap to calculate an accurate quantity. Buying individually from Nottage Timber Merchants means you can order the exact number you need.
