YKK North and Central America Group’s hook and rail fastening system consisting of its POWERRAIL^® SA fastener and POWERRAIL^® holder provides a safe and secure way to fasten and install wall padding in a gym. The POWERRAIL^® SA fastener is  part of our POWERHOOK^® family of continuous injection molded hook products. It is used together with the POWERRAIL^® holder to securely hold the hook onto the wall. The system can be mated with other loops, but we ask that you consult with us so we can provide you with the best combination based on your application and intended usage. Conventional wall padding systems are made with metal holders, which can have sharp edges and adhesive hooks, which can delaminate.  However, YKK’s POWERRAIL^®system is nonmetallic with an extruded hook, eliminating those issues completely.
