RP16 | Astragal | French Door Centre Seal | How To

Pro Tips:

• The difficulty in fitting the RP16 can be quite variable. In the easiest circumstance it is simply a matter of cutting to length and screw fitting to the edge of a door. We highly recommend using a pilot drill to prevent the screw fixings from splitting the edge of the door.
• Things that make fitting an RP16 more difficult include:
• Needing to check in hinges to ensure a minimum 4mm centre gap.
• Needing to rebate the RP16 around a door latch.
• Needing to rebate the RP16 round concealed edge bolts in the top and the bottom of the inactive door
• Best installed on the outside but will need to be installed on the inside if your doors have mushroom stops
• We recommend always drilling pilot holes to position the device and to prevent splitting along the door’s edge.
• The seal should be cut slightly shorter than the full length of the door to prevent jamming at the top or base

There are a couple of limitations with installing RP16 that you need to watch out for:

• You will need a minimum of 4mm centre gap. It’s OK if the gap opens up further but in order for the RP16 not to bind you will need a minimum of 4mm. Sometimes the best way of achieving this is to check in the hinges of one or both of the doors.
• The RP16 can only make up a lateral gap of 7mm. If your active door is not plumb with the inactive door by more than this, then the silicone blade of the RP16 may not seal against part of the active door. It may be necessary to shift the hinges on the active door so that the face of the the two doors are in the same plane.
