Drainage Caps (Pack of 10)

UPVC drain caps are the little pieces of plastic that fit on the front of face drained double glazed doors and windows.


Drain cap holes can be long oval shaped slotted holes or 10mm round holes that allow drainage water to leave the frame.


Drainage caps are available in white or brown and are sold in packs of ten.


There were three shapes originally available which can be described as follows:


  • Round - which are actually octagonal in shape
  • Oblong - which are a long rectangular shape with curved ends
  • Half Circle - which are shaped like a wedge of orange - This shape is no longer manufactured








Half Circle
