For what ceiling height is the Oman Extra attic ladder sized?
The Oman Extra is sized for a maximum ceiling height of 280 cm. It is a three-section wooden ladder, so before choosing, the opening and unfolding areas are checked, not just the height. The official diagram indicates a floor space of 128 or 142 cm and an opening distance of 161 or 165 cm depending on the box length. The dimensions are verified for the specific variant.
What box sizes does the Oman Extra have in LATIVA's product variants?
The Oman Extra variants come in lengths of 110, 120, 130, and 140 cm and widths of 55, 60, or 70 cm. The official catalog defines these values as the external box dimensions and requires an installation opening 2 cm larger. For example, a 120 x 60 cm box requires a 122 x 62 cm opening. The 280 cm height is checked separately from the opening size.
What are the thickness and Ud value of the cover on the Oman Extra?
The Oman Extra cover has a total thickness of 46 mm and contains 40 mm of thermal insulation. The Ud coefficient specified by OMAN is 0.85 W/m²K, the sealing is single, and the cover is white on both sides. These are parameters of the Extra model and should not be confused with those of Maxi, Polar, or Termo PS, which use different thicknesses, insulation, and numbers of seals.
What are the dimensions of the ladder and steps on the Oman Extra?
The wooden ladder of the Oman Extra is 400 mm wide and consists of three sections. The steps are 358 mm wide and 80 mm deep, and the wooden box is 170 mm high. These values help assess comfort and storage space but do not replace the dimensional diagram. During installation, the specific box size and required unfolding area must be observed.
What load does the Oman Extra support and on which side is the handrail installed?
The maximum load for the Oman Extra is 160 kg. The model has anti-slip tips and a handrail, which according to the manufacturer can be mounted on the left or right side. These elements assist support during use but do not compensate for incorrect installation. Before loading, the box attachment to the structure, proper unfolding of the three sections, and stable contact of the tips with the finished floor must be checked.
What is the practical difference between the Oman Extra and Oman Maxi?
The Oman Extra and Maxi are three-section wooden ladders for rooms up to 280 cm, but their covers differ. The Extra has a 46 mm cover, 40 mm insulation, one seal, and Ud 0.85 W/m²K. The Maxi has a 56 mm cover, 50 mm insulation, two seals, and Ud 0.7 W/m²K. The Extra also offers a wider range of box lengths, which factors into the choice.
