We purchased a Vision White Primed 4 Light 1443mm Bifold door, turned up on time, I installed myself, I am confident and skilled in DIY, if you are not get a carpenter to install the door. The Magnetic Tubular Latch With 57mm Backset works well, however the free Sessanta Polished And Satin Nickel Internal Door Handle On Round Rose was not suitable for this door, it did not allow the bifold door to fully concertina when open. We purchased two simple pull handles and fitted them to centre of the outside of the door. Door looks good and operates well, it is adjustable to suit different carpet heights.
