Patio door glass seal perished or letting in water? On many patio doors, a U-shaped gasket wraps round the edge of the glass and seals it in the frame.
We stock Reddiplex R0929 patio door U channel gasket and a U channel gasket sample pack.
Pull out a short length of the old gasket and look at the end. The shape of the cross-section is what you need to match.
Measure the overall height and width, and the leg or foot that pushes into the groove.
Compare your piece with the product diagrams. Reddiplex profiles are listed by R-number, such as R6160.
Measure the thickness of the glass unit. The U channel must suit it.
The gasket wraps round the edge of the glass unit before it goes into the frame. It holds the glass and seals it against water and draughts.
The sample pack lets you check the fit before you buy a full length.
