The Altendorf Hand Guard is unlike anything on the market. Both Sawstop and Felder employ safety systems that require the table saw blade to come in contact with the operator. These safety systems still cause injury, and with loss of downtime and disposables like cartridges and blades on the Sawstop. The Altendorf Hand Guard has all the accuracy, precision, and longevity Altendorf sliding table saws are known for, PLUS the addition of technology that Altendorf has designed not to allow your operator to come in contact with the blade. No interuptions……..no injuries……..just safety and productivity. Once you see a Hand Guard in action, you will see how you CAN NOT afford not to have one!
