When Coram first manufactured their Slimline trays they became very popular and some of the installers asked for a lower height version of their standard riser trays.
So as a listening company, Coram make a kit to allow anyone to add legs to a Slimline tray to make it easy to install and get away with lower height solutions.
Within months they became a best seller and have the benefit of getting the accessibility to the water trap.
Ideal for site conditions such as solid tiled floors, where previously the installer had to make a plinth for the tray to sit on. The "Riser Kit" does this for you with minimum fuss and you can still access the waste, should you drop something into the trap that needs to be retrieved like a precious wedding ring !
All in all a great product derived from customers requests, which shows Coram are a "listening" UK manufacturer.
