Engineered for the concrete professional, our Allen® Walkers are designed to produce high tolerance concrete floors (as measured by F-Numbers) with high quality features that are hard to find on other trowels. Allen Pro-Series Walkers feature precision engineered Allen Gearboxes for long, trouble free life. We use cast iron spiders, pressure plates and lift levers for long wear and continuous service. We precision machine our trowel arms and spiders to such close tolerances that our trowels don't need bushings. And, our high strength steel handle provides maximum comfort and control. Our commitment to product quality, attention to detail and 100% product testing ensures that your Allen Walker wil provied you with years of high performance and trouble free operation on the job.
