This is a bumper strip that can be applied at any height and on any surface; it has the advantage of protecting the walls only at the height desired. The density of the compost is such to allow the material to be elastic, so it will therefore keep the same appearance after being knocked. It is particularly suitable for use on plate or fibreglass reinforced plastic walls where it is preferable to apply a fixing system that does not have to resort to wooden blocks or mechanical brackets.
