Casing height up to 80 cm.

It is possible to design the Made-to-measure loft ladder with a casing height of up to 80 cm. Casing heights over 36 cm are fitted with an extra tread in the casing. If the casing height is above 65 cm, 2 treads must be installed to comply with building regulations. The casing is white primed plywood.

The difference between ceiling opening and casing dimensions?

We use the term " ceiling opening ". The term refers to the size of the opening in the ceiling where the loft ladder will be placed.

The casing dimensions are the length and width of the casing of the loft ladder.

Our loft ladders are produced 2.5 cm smaller than the hole size you order, this ensures that there is a gap for the loft ladder to be installed.

If you have any questions, please feel free to contact our customer service on Tel: 01376 528000.

Please note that this is a made-to-measure product and therefore cannot be returned or cancelled after purchase.
