ABSTRACT:
A stair support device is provided for installation on the upper surface of an inclined stair stringer. The device is foldable from a sheet metal template so as to define right-triangular first and second spaced-apart vertical sidewalls, positionable with their hypotenii along the stringer, the sidewalls being joined by an integral horizontal stair support surface. Preferably, the device further includes at least one and preferably two generally right-triangular support webs extending downwardly from against the stair support surface, positionable with their hypotenii on the upper surface of the stringer, thereby serving a load-bearing function between the stair support surface and the stringer. Various fold-out tabs are provided, to facilitate securing the device to the stringer, the stair against the stair support surface, and if applicable, a riser or kickplate against a vertical face of the device.
