How long does the Water Door Closer take to shut a security door?
• Typically a 1200mm wide sliding security screen door will be closed in 4-7 seconds from the fully open position. If the door closes too fast the smaller of the two weights in the closer can be removed. If it closes too slowly a further small supplementary weight can be added but this should be done only after checking the door rollers and tracks for cleanliness and the door rubbing against the sides of tracks.
