Flat fir handrail 70x28 mm
Flat handrail in solid fir, 70x28 mm, with a 19x5 mm groove for fitting to standard brackets. Its flat profile provides a wide, stable grip, unlike round or moulded profiles. Available in 4 lengths: 150, 200, 250 and 300 cm. Can be cut to the exact length required. Sanded, untreated wood: paint, varnish or apply a wood stain before installation. For indoor use only. Order brackets compatible with a 19x5 mm groove and fixings separately – note that this groove differs from the range’s 21x5 mm groove.
Flat fir handrail, 70 x 28 mm flat profile, 19 x 5 mm groove
This flat 70 x 28 mm solid fir handrail is designed for indoor staircases, balustrades and corridors. Its flat cross-section, 70 mm high and 28 mm thick, provides a broad, stable grip unlike the cylindrical profile of round handrails. The 19 x 5 mm lengthwise groove allows it to be fitted to standard wall or stair-mounted brackets.
Fir is a lightweight softwood (around 450 kg/m³), easy to cut and finish on site. Supplied sanded and unfinished, it accepts all types of interior finish: varnish, oil, wood stain or paint. It is for indoor use only – without a suitable specialist treatment, outdoor moisture would cause warping and accelerated deterioration.
Four lengths are available: 150, 200, 250 and 300 cm. All can be cut to size with a saw. Mounting brackets are not supplied – they must be compatible with the 19 x 5 mm groove, which differs from the 21 x 5 mm groove on other profiles in the range. Check this before ordering if you already have brackets installed.

Installation tips
First, check that your brackets are compatible with this model’s 19 x 5 mm groove (not 21 x 5 mm). Position the brackets at regular intervals, with a maximum of 80 cm between support points. Two brackets are enough for lengths up to 200 cm. For 250 cm and longer, allow for an intermediate bracket.
Fix the brackets using fixings suitable for the wall material – concrete wall plugs, expanding plasterboard fixings or screws driven directly into a wooden stud. Install the handrail 80 to 100 cm above the stair nosings or finished floor. Fit the groove over the bracket heads, then tighten the screws without overtightening (fir is soft and marks easily).
If you need to cut it to size, use a fine-toothed saw for a clean cut. Sand the cut end with 120-grit sandpaper before applying the finish to protect the exposed wood.
Care and protection
Unfinished fir must be treated before regular use. We recommend applying the first coat of finish before installation, while every face is still accessible – including the groove and the ends. Options depend on the appearance you want:
- Polyurethane varnish: 2 to 3 coats, lightly sanding between coats, for optimal resistance to rubbing; lasts 5 to 7 years
- Hardwax oil for interior wood: natural matt appearance; reapply every 2 to 3 years
- Interior wood stain: penetrates the wood, can add colour; reapply every 3 to 5 years
- Interior wood paint: apply after a pore-filling primer to add colour that suits your décor
For routine care, regular dusting and wiping with a slightly damp cloth are enough. Do not clean with large amounts of water. Periodically check that the retaining screws on the brackets are tight.
WoodUp tip
Before you buy: the flat 70 x 28 mm profile provides a broad, stable grip suitable for heavily used staircases. Compatible with WoodUp brackets for a 21 x 5 mm groove. Wall fixings are not supplied. Treat every face before installation, including the underside groove. Indoor use only.
Frequently asked questions
What is the difference between a flat 70 x 28 mm profile and a moulded or round profile?
The flat profile is gripped from above, with the palm resting flat on the 70 mm surface. This provides a different type of support from round profiles (a cylindrical grip) or moulded profiles (a grip from the side). Flat profiles are often used on wall-mounted balustrades or handrails where a simple, linear appearance is desired. Their flat faces also make them easier to paint evenly.
Is the 19 x 5 mm groove compatible with standard brackets?
Yes, but note that this model has a 19 x 5 mm groove, unlike the 21 x 5 mm groove on most other handrails in the range. Before buying brackets separately, check that they are designed for a 19 mm-wide groove. Brackets available from Woodup for this model are listed in the accessories section.
Can this handrail be cut to a length between the available sizes?
Yes. Solid fir is easy to cut. Use a fine-toothed saw to avoid splintering the visible faces. After cutting, sand the cut end with 120-grit sandpaper, then apply a coat of finish to the ends to protect the exposed wood. The flat profile makes it easier to cut at right angles than a round handrail.
Is this handrail suitable for a heavily used staircase?
Fir is a soft wood (density approximately 450 kg/m³) that can become marked through heavy use or repeated knocks. A polyurethane varnish finish significantly reduces surface wear. For a heavily used staircase, beech or oak offers much greater resistance. This model is well suited to domestic staircases with normal everyday use.
What installation height is recommended for an indoor handrail?
For a domestic staircase, the recommended height is 80 to 100 cm, measured from the stair nosings. For a corridor or landing, measure from the finished floor. For people with reduced mobility, a height of 90 cm is generally recommended, with an uninterrupted handrail along its full length.
Why choose fir rather than a denser wood such as beech?
Fir is considerably lighter and more affordable than beech. It is easy to cut and finish, making it a practical choice for DIY projects. However, it is a soft wood that marks more easily. Beech is preferable for heavily used staircases or interiors where abrasion resistance is a priority. For normal domestic use, fir is a suitable, economical choice.
