Description

The McStep Thermo 33 is Minka’s most affordable attic ladder. It is not supplied fully pre-assembled, so you should allow a little more time for installation. A steel safety handrail and matching ladder feet are available separately and are not included.

A wide range of sizes

The McStep Thermo 33 is available for ceiling openings measuring 90 × 60 cm, 90 × 70 cm, 90 × 80 cm, 110 × 60 cm, 110 × 70 cm, 110 × 80 cm, 110 × 90 cm, 120 × 60 cm, 120 × 70 cm, 120 × 80 cm, 120 × 90 cm, 130 × 70 cm or 140 × 70 cm.

It is suitable for room heights of up to 280 cm. For lower rooms, you can simply shorten the solid wood ladder by cutting it to the required length.

Well insulated and sturdy

With its 33 mm thick lower hatch panel, the McStep Thermo 33 achieves a U-value of 1.1 W/m²K. The 27 mm thick treads are designed to support loads of up to 150 kg.
