This sliding door limiting stay is a very simple and effective way of avoiding damage to outward opening doors, which can get caught in sudden gusts of wind. The limiter channel simply slots into the groove which is found on all uPVC door frames then secured into place with the screws provided.
From the channel there is a stainless steel arm which is mounted under the head of the frame. Once secured, the door will open and come to a stop at approx 90degs.
Good product. Shame about the lack of fitting instructions. Whilst it is obvious what goes where an initial starting point (dimension from edge of frame) would not go amiss and save a lot of guesswork,
