The barrier seals against the flat outside surface of the doorframe and down onto the step (stone, concrete or wood) as shown in figure W1.
The barrier should overlap onto the doorframe approx 1 ½ inches (38mm) each side of doorframe to allow the barrier to clip to doorframe as shown
Clip arrangement – Figure W2
Fig W3 and W4 shows an example of part of the doorframe outside being hidden (narrow). This is a result of the outside wall being rendered in sand and cement coating/pebble dashed. By adding a wood batten to the doorframe (as shown fig. W3 and W4) it will allow the barrier to clip to the doorframe. (wood batten can be painted to match the doorframe).
