Adapting the trapdoor

The loft ladder is suitable for a loft opening let flush

into the ceiling, having a hinged trapdoor opening

downwards, with a suitable fastener to keep the hatch

firmly shut. If the trapdoor does not hinge downwards,

or is not hinged at all, you will need to adapt or replace

it so that it does. The parts needed are enclosed.

Hanging the trapdoor

Minimum

of 1" (26mm)

Use the existing cover as a template to cut

out the new piece, ensuring a slightly loose fit all

round, (3mm (

”) maximum). Your DIY store may be

able to do this for you.

1.2

Remove the existing trapdoor and hinges.

Prise off any support battens so that the four faces of

the loft trap frame are flat.

1.3

Screw hinges (G5) to one edge of the

trapdoor using 20mm (

”) wood screws

1.4

For extra performance fill the screw holes with

wood glue.

1.5

Offer up the hinges to the face of the frame on

the same end as you intend setting the ladder, and fix.

1.6

Ensure that there is at least 26mm (1”)

clearance between the top face of the trapdoor and

the top edge of the framework.

1.7

Fitting the Twist Catch

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.

2.1

With the trapdoor fully closed measure

exactly 26mm (1”) in from the edge of the frame and

mark with a pencil.

2.2

Drill a 13mm (½”) hole in the centre and sand

off any rough edges.

2.3

Pass the catch operator (A1) through the

trapdoor hole from the underside such that the

position pointer points towards the trapdoor edge.

2.4

Place the travel stop ring (A2) over the

operator such that the securing tag is at 45 degrees

to the trapdoor centre line.

2.5

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).

WARNING:

Do Not stand on the ladder to do this. Either using a

second ladder, or from inside the loft space, secure

the hinges using six 35mm screws supplied.

If flooring material covers the top edge of the loft hatch frame ensure that it is completely stable and if necessary

use longer screws to penetrate the frame itself.
The ladder should now be free to swing from the hinges and slide freely up and down the guides.

Installing the Ladder

N.B.

The ladder should be installed on the same side

of the trap as the trapdoor hinges.

With the ladder preferably centred in the

opening, and the trapdoor hanging down, locate the

hinge guide bracket arms (B1 & B2) on the top edge

of the loft hatch frame (see diagram).

Make guide holes with the bradawl then pre

drill pilot holes (2mm diameter) for all screws.

Fix using 35mm screws (B3).

N.B.

the bracket arms with two screw holes should be

on top.
