This headrest is installed on Fonteyn, Passion Spas, Ligne Spas and Wellis spas, among others. It is fixed in place with two holes in the slots provided on the shell of your spa, or with suction cups.
Since headrests can react badly when the free chlorine level in your spa is higher than 3 ppm, Tubs Parts recommends that you remove them when they are not in use.
Distance between fixing points: 198 mm (two suction cups)
