A classic oak look that ages beautifully - thanks to natural oak construction

Supplied unfinished, the timber will turn golden brown when treated with oil, wax, stain or varnish. Natural oak grain and open pore structure accept traditional finishes that alter tone and sheen.

A finished surface creates a warm, traditional focal point on a staircase, allowing colour matching to existing joinery and a bespoke end result.

Robust, weighty feel for long-lasting support - with high-quality oak construction

Manufactured from solid oak, the cap delivers natural density and structural rigidity, a fact echoed by user feedback noting solid weight and good manufacture. The timber's strength helps maintain shape and finish over time.

A sturdy top gives a more substantial finish to the newel, remaining tactile and secure under normal household use.

Straightforward retrofit for existing posts - with a 5mm rebated underside to fit 90 x 43mm posts

Underside is rebated 5mm deep to sit over a 90mm x 43mm newel post, designed to be glued into position using PVA wood adhesive. The rebate allows a flush sit and clean sightlines at the junction.

Slides over standard posts for tidy installation and a secure bond once glued, making it suitable for updating existing staircases without complex joinery.
