"Just fitted one of these and it works great. I certainly didn't have to remove my door as others have suggested. Simply removed my old one, cut the new one to fit, placed mastic around all the contact surfaces, screwed it down then applied mastic to all edges. Even with all this really bad weather not a drop of rain came in and no evidence of draughts either. Great value item!"
"this is a good product, i bought this for a rear (exterior) door. If you are fitting on an existing door (rather than a new dorr as a I did), then bear in mind that you will need to remove the dorr and cut from the bottom, before fiting this."
