Abstract: An adjustable-width barricade for removable installation at the bottom of a staircase includes a flexible, frameless, planar, and generally-rectangular barrier member that extends between two posts on either side of the staircase. The barrier member is installed in a banister-to-banister configuration, a wall-to-banister configuration, or a wall-to-wall configuration. The barrier member has a front and back surface that forms an interior space therebetween. The adjustable-width barricade further includes a plurality of fasteners extending from one or both sides of the barrier member for tensioning engagement between one or both posts that maintains the lateral or horizontal integrity of the barricade.

Abstract: An adjustable width barricade includes a frameless, flexible, washable, aesthetically attractive, and generally-rectangular barrier that mounts between banisters of a stairwell. The adjustable width barricade does not require drilling into the stairwell banisters and is removeably mountable without damaging either the structural integrity or decorative finish of wooden banisters, balusters, rails, or posts. Multiple strap-like fasteners attach the barrier to stairway banisters or posts, including posts having vertically varying diameters and configurations, that are non-parallel relative to each other, that are non-perpendicular relative to the flooring surface, or that are otherwise asymmetrical. A plurality of rigid, structural support members are inserted into vertical channels in the barrier that maintain the height of the barrier when installed.
