FIELD: construction, particularly stair step structure, namely antiskid members for existent staircases.
SUBSTANCE: L-bar comprises working strip of elastic material provided with serration on outer surface thereof and two embedded members projecting in vertical and horizontal planes. The embedded members are made of metal alloy or of plastics. Working strip in vertical extension is connected to front edge thereof and in horizontal extension is arranged at rear working string edge. Two longitudinal cavities with slots opened downwards are created in the strip. The slots enclose and retain oval ends of embedded members. Working strip is made of silicone rubber, which may be colored, rubber or elastoplastic material. Strip material may also include filler, namely luminophor.
EFFECT: increased wear resistance of working device part, elimination of joint erosion, increased reliability of L-bar contact with floor panels, improved simplicity of working part installation and replacement in wide range of existent stair steps and stair steps under construction.
