Adapting the trapdoor
The loft ladder is suitable for a loft opening flush with
the ceiling, having a hinged trapdoor opening
downwards, with a suitable fastener to keep the hatch
Hanging the trapdoor
1.1
If a new trapdoor is required, its thickness
must not exceed 20mm (3/4"). Consider the weight of
the trapdoor and the security of the hinge screws.
Chipboard and MDF may not be suitable.
1.2
Use the existing cover as a template to cut
out the new piece, ensuring a slightly loose fit all

Ensure that there is at least 26mm (1")
clearance between the top face of the trapdoor and
the top edge of the framework.
Fitting the Twist Catch
2.1
Find the mid-point of the trapdoor edge
opposite to the hinged side. This will give you your
centre line (see diagram). Mark with a pencil.
2.2
With the trapdoor fully closed measure
exactly 26mm (1") in from the edge of the frame and
mark with a pencil.
2.3
Drill a 13mm (½") hole in the centre and sand
off any rough edges.
2.4
Pass the catch operator (A1) through the
trapdoor hole from the underside such that the
position pointer points towards the trapdoor edge.
2.5
Place the travel stop ring (A2) over the
operator such that the securing tag is at 45 degrees
to the trapdoor centre line.

Place the catch lever (A3) over the operator
and locate into the operator groove such that the
lever points towards the trapdoor near edge and fully
locates within the travel stop ring (A2).
