IMPORTANT
Strong springs aid the operation of these ladders! Care must be exercised during
installation and operation so these springs are not released in an uncontrolled manner as
this could lead to damage to the ladder and personal injury to the operator/installer.
These instructions are not intended to be a complete lesson in the installing of attic
ladders but a procedural guide to competent tradespeople or DIYers.
TOOLS REQUIRED
The timbertight screws supplied with this ladder require a 5/16” socket for easy
installation. This can be used with a 9 volt (or stronger) battery drill or a standard power
drill. Apart from this, only standard carpentry tools are required.
CHOOSING THE LOCATION
When choosing the location for the installation of the attic ladder, a compromise
possible in relation to the roof structure may be required. The considerations for this
compromise are:
• Choose a location that will give good head room at the top of the ladder;
• Choose a location with good access at the bottom of the ladder;
• Choose a location that will allow for movement around the ladder when in the down
position;
• Allowance must be made for the operation of the ladder, as it requires a greater

PREPARING THE OPENING
1. Mark out on the ceiling the opening required for the model ladder purchased in the
selected position. Cut out the ceiling lining ensuring that the opening is square.
2. Using timber of a compatible size to the existing ceiling framing (ie 90 x 45 or 140
x 45 H1.2 treated, machine gauged radiata pine), frame up the opening. It may
be necessary to cut through some existing ceiling joists to achieve the required
size. Ensure these are properly supported during and after cutting. Three possible

3. Turn the lid over so the lid is facing up. Fit the screw eye 100mm in from the opening
INSTALLING THE LADDER
1. Screw four temporary cleats approx 80mm x 40mm into your timber frame as shown
Note: If the ladder is to be installed before the ceiling lining is in place, the cleats
must be packed down the thickness of the intended ceiling lining.
2. Lift the ladder through the opening into the attic space. Then lower down squarely
into the opening so the lid of the ladder rests on the temporary cleats. This is
normally best done from below. For safety and ease it is highly recommended that
two people complete this step. Rotate the cleats off the lid and onto the frame of the
ladder.

making sure there is solid timber behind. Screw through the pre-drilled holes into the
