The Story
Decking handrail infill in 15mm x 41mm section slots into the groove of a matching handrail to space, align and secure balustrade spindles for a neat, professional finish. Supplied in 4.2 metre lengths, it suits both DIY and trade decking projects.
Specifications
| Property | Detail |
|---|---|
| Nominal Size | 15mm x 41mm |
| Length | 4.2 metres |
| Profile | Flat infill strip, groove-seated |
| Material | Timber |
| Use Class | External (UC3, covered deck/rail application) |
What it's used for
- Spacing and securing vertical spindles within a decking handrail channel for a consistent, even balustrade layout
- Infill for raised deck perimeter rails where Building Regulations require a guarded edge
- Stair balustrade rails on external timber staircases where spindle alignment is critical
- Cut into individual spacer blocks to allow spindles to float freely, letting the timber move with seasonal moisture changes and reducing the risk of splitting
Fitting and handling
Allow the infill to acclimatise outside, under cover, for at least 48 hours before installation so the timber stabilises to site conditions before fixing. The strip can be fixed continuously along the groove to pin each spindle in place, or cut into short spacer blocks between spindles if you prefer to let the timber breathe and move with the weather. Once fitted, apply a good quality exterior wood oil or decking finish to all cut ends and exposed faces to reduce moisture uptake and extend service life.
FAQ
What is decking handrail infill used for?
Handrail infill sits inside the routed groove of a matching handrail profile. It acts as a spacer and retainer for balustrade spindles, keeping them evenly spaced and upright without the need for individual fixings through the rail face.
Can I cut the 4.2m length into shorter spacer blocks?
Yes. Many builders prefer to cut the infill into individual spacer blocks rather than running it as a continuous strip. This allows each spindle a small amount of movement as the timber expands and contracts seasonally, which helps prevent the rail from splitting over time.
Does this infill need treating before use?
Treat all cut ends with an end-grain sealer or exterior wood preservative before fitting, and apply a suitable decking oil or finish once the balustrade is assembled. This is particularly important in the exposed South Wales coastal climate where timber sees heavy moisture.
