Does your doorstep make it difficult for you to create a tight seal on your door bottom in spite having a Draught Excluder in place? The RP48B Door Threshold Plate will straighten out uneven doorsteps and help reduce the gap size on the bottom of your external door. The RP 4B, being quite a versatile treadplate, allows you to totally block out draughts from your living spaces.


How it Works:

A high qualitdraught proofing solution for door bottoms, the RP4B is an aluminum door threshold plate designed to run along the doorstep and meet the appropriate draught excluder. It can be cut to size during installation. 

This product is used to straighten or increase the height of the step to allow the appropriate draught excluder to effectively prevent draughts from your door bottom.


  • Aluminium construction with a integral sill gasket
  • Used in conjunction with other raven draught excluders, particularly the RP3 and RP35 
  • Architectural quality
  • Durable
  • BAL FZ when used with a BAL rated door bottom seal. 


  • Does not interfere with the opening and closing of the door
  • Raises the height of the door step by up to 16mm

 Suitable For:

  • Bottom of door to raise up the door threshold

How To

What you will need:

  • Alcohol wipes or microfibre cloth with methylated spirits

    How to Install: 

    This is one of the new products we have that does not include an installation video.  That's because it is SO easy! 

    Q: How is the RP4B fixed to a hardwood threshold? 
    A: After cutting the RP4B to length, use a pencil to mark the screw points on the threshold. Ensure you pilot drill the threshold with a 3.5mm drill bit so that the screws are more easily fitted.

    Q: How can the RP4B be fixed onto a stone threshold?
    A: Once the RP4B is cut to length, place it on the threshold and mark the screw points with a nail and hammer through the fixing points. Remove the RP4B from the threshold. Using a 6mm masonry drill bit, drill each fixing point for sufficient depth to take the fixing screw. Fill each hole with red spaghetti or similar, put the RP4B in place and fit the fixing screws into the red spaghetti. If the stone threshold is not flat, be sure to fix carpenter's packers under the RP4B such that as the screws are tightened, the treadplate remains flat.

    Pro Tips: 

    • Surfaces must be clean and smooth to ensure good adhesion.


    Q: What is the Raven RP4B threshold plate made of?
    A: The Raven RP4B threshold plate is made of high-quality anodised aluminium which ensures its durability and resistance to wear and tear over time.  That is critically important for a treadplate. 

    Q: How does the Raven RP4B threshold plate help prevent air and water leakages?
    A:  By creating a flat surface at the door step for a draught excluder to fit snugly to.  The RP4B is not preventing air and water, but is facilitating the draught excluder to effectively do its job.
