Wooden Door Frame (Narrow frame) less than 1 ½” (38mm) Figure 4


The barrier seals against the flat  outside surface of the doorframe and down onto the step (stone , concrete or wood) as shown.

Fig 4 and 4a 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. 4 and 4a) it will allow the barrier to clip to the doorframe. (wood batten can be painted to match the doorframe).
