are required. If you fit the attic ladder at right angles to the

joists, you will need to make double transverse joists of the

same size as the existing ceiling joists.

WARNING: If the ceiling joists are made in a material other

than timber, e.g. steel, contact a qualified craftsman. Ne-

ver saw through a load-bearing joist without advice from a

qualified craftsman. Take great care when sawing ceiling

joists. For safety's sake, if there is no attic flooring, lay planks

a cross the ceiling joists to allow safe passage in the attic

during installation.

4. Fitting temporary supports:

To keep the attic ladder in place in the ceiling opening during

installation, you are advised to fit temporary supports. If the

trapdoor will be clad, the attic ladder must be fitted as many

mm higher in the opening as the thickness of the cladding.
