Using your AltaFLEX Knee Protectors is easy. First, adjust the fasteners to fit your knees comfortably. Make sure the long cap is properly placed over your knee for maximum coverage. You can choose either the AltaLOK locks or the AltaGrip fastening systems according to your preference. When using them, avoid sharp objects that could damage the Cordura Nylon cover. After use, clean the knee pads with a mild soap and water. Let them dry naturally. Don't machine - wash or dry them as it may damage the padding and liner. Check the brass grommets and fasteners regularly for any signs of wear and tear. If you notice any issues, contact our professional support team for help.
