Picture Rail for Square-set ceilings (no cornince):
Locator extraThe Locator Extra system has an extra high face which enables installation tight to a straight Square-set ceiling when there is no P50/P60 shadowline. If there is a shadowline in place we normally recommend preserving this feature and coming down the wall from the ceiling line a minimum of 15mm.
Locator Multirail extraThe Locator Minirail extra is based on the above rail, with the same function of the extra piece on the top of the rail allowing installation tight up underneath a square-set ceiling. This rail has an inbuilt 12v strip that with the use of a transformer can be powered to provide lighting to pictures from the same picture rail.
