Sugatsune Concealed Straightener Bar for Large Doors

Large area where design has caused issues for installers is with the evolving trend for ever larger cabinet and wardrobe doors.
Larger doors however put a greater stress on the fittings and materials used to produce them. One possible result, particularly with composites, is that the door will warp.
In Europe where they have been making doors from thinner materials for some time, it is standard practice to reinforce with tensioner bars. Fortunately, Sugatsune has found a solution that prevents warping. The whole system can be also completely concealed. The TN423 is a tensioner bar that is adjusted with an Allen key from the top edge of the door. Info
The rod has a threaded sleeve section, when turned by a hex key from the end applies tension or compression to bring the door back to straight and true. The TN423 can be cut down by 400mm so that one size can often be stocked to cover a wide range of differently sized doors.
