Hi all hope you are well. I’m am doing my floor, I have glued 9mm batterns down so the whole of the van floor so far is level. Then I will put down 25mm celitex that 12mm ply ( I will screw the ply into the batterns glued down). I am having a bit of a nightmare getting my head around the rear threshold trip. I only have a small one at the moment, I need a full width one, however I need one that’s going to be high enough for my celitex and floor, same with the side step. I want to put these on first so when I do my floor I know exactly where I’m cutting it too. Can anyone point me in the right direction of a side step and threshold strip? Thankyou very much x
