Professional installers and DIYers, this Roberts 3-1/2 inch stair tool is an absolute essential for anyone working with carpet on stairs! The chrome-plated steel construction is built to last through years of tough use without rusting or deteriorating. The checkered head design is genius - it prevents your hammer from slipping when you're tapping the tool to secure carpet into tack strips, which is crucial for safety and precision. The cushioned, slip-resistant handle makes it comfortable to use for extended periods, reducing hand fatigue during big jobs. The heavy-duty blades are perfectly designed to easily set carpet into those tricky stairway crevices and corners where other tools just don't work as well. It's not just for stairs though - you can use it to drive carpet into gullies, crease carpet along wall lines, or set carpet into any tight spaces where you need that extra leverage. The 3-1/2 inch width is ideal for getting into stair corners while still providing enough surface area to work efficiently. The forged steel construction means this tool can handle serious pressure without bending or breaking. Whether you're a professional flooring installer or a homeowner tackling a stair carpeting project, this tool makes the job so much easier and gives you professional-looking results. It's one of those specialized tools that seems simple but makes a huge difference in the quality and ease of your carpet installation work.
