Quarter-turn top staircase NERONNE Fir

NERONNE Top Quarter-Turn Staircase - Solid Fir, 280 cm, 13 Treads

The NERONNE top quarter-turn staircase in solid fir is designed to connect two levels while optimising the available opening. Its top quarter-turn configuration means that the 90° change of direction is located at the top of the flight, just before reaching the landing. This configuration is particularly suitable when the opening is offset relative to the main axis of ascent, or when the starting room requires setting off in a different direction from that of the opening.

Designed for a floor-to-floor height of 280 cm with 13 treads and a tread height of 20 cm, the footprint is 287 cm in the direction of ascent. The recommended opening is 85x287 cm minimum. Tread sections: 200x28 mm with risers / 200x32 mm without risers. Available in right or left hand, with or without risers and handrail.

Installation advice

Determine the direction of the quarter-turn before ordering: top quarter-turn right or left. To find out, imagine yourself at the top of the staircase facing the landing — the direction of the turn corresponds to the side towards which you turn to reach the landing. This choice is final at the time of ordering.

Check the opening (85x287 cm minimum) on finished dimensions. The handrail is not reversible on this staircase: the installation side is linked to the direction ordered. If a handrail is planned, fit it during assembly: the quarter-turn newel post acts as the handrail newel post and must be managed from the assembly stage. Fix the staircase to the floor, to the opening, and to the wall in accordance with the instructions.

Maintenance and protection

Apply an interior finish before first use. For fir, a 2-coat staircase varnish provides effective protection (renewal every 5–7 years); an oil-wax is suitable for lighter use. Routine cleaning with a dry cloth or slightly damp cloth. Check the tightness of fixings once a year.

WoodUp Advice

The difference between top quarter-turn and bottom quarter-turn is not merely aesthetic — it determines the position of the opening within the room. A top quarter-turn is often chosen when the ascent runs along a wall and the opening is in line with the arrival corridor, with a lateral offset at the top. Draw a plan of your room with the opening before choosing between bottom and top — a wrong choice of direction means having to reorder the staircase.

Good to know before purchasing: the handrail is not reversible on this model — the handrail side (right or left) is directly linked to the direction of the staircase ordered. Please check the required direction carefully before confirming the order.
