Several of the white round drainage baffles / plugs are missing in the bottom of my old, but otherwise in very good condition double glazing units. Can you help tell me where I can buy these drainage baffles / round plugs from. Also do they have another name? Thanks Steph
these are known in the trade as face drain caps i would just call in at a local window manufacturer maybee take one of yours with you and ask if you can buy some
