Internal Polyboard Window Cill End Caps


These interior window board end caps are 400mm long, with a double ended finish so one end cap could be used to cap two board ends!  Designed to fit standard 23mm thick window board these end caps come with either a gloss finish or are foiled with a grained finish to perfectly match your cill board.


  • White - PVC Gloss finish
  • Golden Oak - foiled grain finish
  • Rosewood - foiled grain finish
If you are unsure which colour will best match your board then please feel free to contact us.

These end caps are easy to fit and can be stuck to the window board using superglue.  For best results we advise using SilverSil superglue and Activator.
