(Consider an RP3 for s single door or Draught Dodgers for French Doors for double doors).
• Can be used successfully on the bottom of hinged doors that open over short pile carpet.
• It is also suitable for draught proofing external sliding doors. In this situation it is usually fitted flat on the tread so that the brush rubs gently on the face of the door and similarly on the head of the door. In these cases the brush seal should be screw fixed. (Screws are not included).
• In some cases a brush seal can also be used on the back edge of external sliding doors to seal against the timber edge of the sidelight. (RP5 can also be used for this purpose).
• When used externally the RP15 should be screw fixed. The self adhesive should not be relied upon when exposed to weather.
