  • Patent number: 6141920
    Abstract: A stair edge profile assembly comprises a tread angle member having a tread limb portion whose free end is in the form of a cover blade member extending over a stair tread covering. The tread angle member carries an abutment limb substantially at a right angle to the cover blade member. The assembly further includes a base profile member which can be fixed on the stair structure. The tread angle member can be fixed on the base profile member by way of a holding means affording adjustment in height, so the height of the tread angle member can be so set in dependence on the thickness of the material of the tread covering that the cover blade member comes to lie on the tread covering.
