The removable wear sheet is designed to Velcro securely in place and can be exchanged if excessive wear occurs, without having to replace the main mat. The underside of the mat is equipped with a perimeter of Shoregrip which assists in positioning on smooth surfaces prior to securing. The Modular Mat System also has a molle looping system along the perimeter which allows the optional roller kit to easily attach in position utilizing non-locking carabineers, 6mm cord and 4mm prussiks. The roller kit helps to maximize efficiency with heavy raises and reduces unnecessary wear on the mat system. The Modular Mat System is available in both 16” x 24” and 16” x 36”.
