Carlisle's Rubber Paver Edge Restraint is manufactured from .080 gauge aluminum and is specifically designed for use with Carlisle's Rubber Pavers. The Rubber Paver Edge Restraint provides a solid border to terminate Carlisle Rubber Paver systems, preventing separation that can occur due to expansion and contraction. The Edge Restraint is used when there is an absence of a solid curb or parapet for the Rubber Pavers to butt against. Carlisle's Rubber Paver Edge Restraint is designed to sit 1/4" below the top of the Rubber Pavers to prevent it from being a tripping hazard and has built-in drainage slots to facilitate drainage under the Rubber Paver system. The Rubber Paver Edge Restraint is available in straight sections as well as 'easy-bend' sections to allow for the creation of curves and other non-straight edge shapes.
