    Heavy Duty Ribbed Thresholds

    Image of Product. Front orientation. Thresholds. Heavy Duty Ribbed Thresholds.
    Strong enough to handle forklifts and heavy vehicle traffic, these thresholds add a slip-resistant bridge between flooring surfaces. They’re 10 times stronger than standard thresholds and provide more grip than smooth thresholds.
    Grit-Coated Aluminum—Grit-coated aluminum thresholds have a sandpaper-like texture for traction in wet and oily conditions. This coating also adds durability to these thresholds, so they last longer than uncoated aluminum versions. However, it makes them difficult to cut and drill.
    ANSI/BHMA A156.21—ANSI and BHMA certified, these thresholds have been tested to withstand compressive loads.
