If I need a heavier duty roller would I be looking at the R80.24? To support the bottom of the door can you please confirm what parts I need, I’ve been looking at the BK4?

Yes, the R80 can take up to 80kgs per door, all the weight is taken by the top track & carriage.  If you want a full length floor guide, you can use the BK4 Bottom guide kit with it.  The Rollan kit does come with short metal floor guides, which are designed to be used in conjunction with a groove which you have to mortice into the bottom of the door.  If the door doesn’t travel more than it’s own width, then the invisible Rollan floor guide is the best & most elegant thing to use.
