What kind of ladder and steps does Oman Solid Polar use?
Oman Solid Polar features a three-section metal ladder, 400 mm wide. The usable step width is 361 mm, the depth is 80 mm, and the wooden box is 170 mm high. The metal structure differs from the wooden ladder in the standard Polar. When choosing, not only the material and size of the opening are checked, but also the free space needed for unfolding the three sections.
What kind of hatch does Solid Polar have and how many seals does it use?
Solid Polar is equipped with an 86 mm hatch, 80 mm thermal insulation, and two peripheral seals. OMAN specifies Ud 0.36 W/m²K and white color on both sides of the hatch. This is the thermal configuration of the Solid Polar model. It should not be confused with Solid Extra or Solid Termo, which have thinner hatches, less insulation, and different Ud values.
What box sizes are available for the Solid Polar attic ladder?
The size range of Solid Polar includes lengths of 113, 120, 130, and 140 cm and widths of 55, 60, or 70 cm. These are the external dimensions of the box, and the installation opening must be 2 cm larger. For the 55 cm width options, the manufacturer notes that a railing cannot be installed, which should be considered when choosing the size.
How is the unfolding space for Oman Solid Polar checked?
The maximum room height is 280 cm. For a box length of 113 cm, the technical table shows floor space of 139 cm and opening distance of 165 cm; for lengths 120-140 cm, the values are 147 and 169 cm. These dimensions are measured on the finished floor and are separate from the attic opening. The full trajectory must remain free for the three metal sections.
What is the maximum load capacity of Solid Polar and how is it equipped?
The maximum load capacity of Oman Solid Polar is 210 kg. The catalog lists a railing, safety caps, and an additional step, but for the 55 cm width, a railing cannot be installed. The load capacity is a characteristic of a properly assembled and secured ladder, not a permission to use it partially unfolded. After installation, the support to the floor and the fixing of the box are checked.
How does Solid Polar differ from the metal ladder Solid Extra?
Both models have a three-section metal ladder, 400 mm wide, a 170 mm box, and a maximum load capacity of 210 kg. The main difference is in the hatch: Solid Polar has an 86 mm hatch, 80 mm insulation, two seals, and Ud 0.36 W/m²K. Solid Extra has a 46 mm hatch, 40 mm insulation, one seal, and Ud 0.85 W/m²K. Their shortest size ranges also differ.
