Suitable for warped doors either through installation, heat expansion or other forms of weather damage. If doors are left untreated it is a good idea to use this.
Installation will be simple: use a similar size of timber that matches your current door and screw that on with the under lapped side, screwing the twist shutter on the side closest to the other door will help keep the two doors in place.
With the turn button in place and security the warp door, within a couple of months the warp should be less noticeable/removed.
