record-usa is proud to introduce our Stormcord series of hurricane resistant sliding door systems. The record 5400 Large Missile Impact Series and the record 5500 Wind load series have both been tested to rigorous Florida State and Dade County criteria and offer the same fluid, quiet and reliable operation that the record 5100 Series is known for. The 5400 series has been tested to design loads of +65/-70 PSF (NOA 15-0316.04)
