Residential doors with sidelights do not have as much depth in the structure of the doorframe support as Doors with standard Stud Walls. We designed a shorter pin extension secured with a stainless steel fastener. This reinforces the doorframe without breaking into the sidelight glass. Just as the standard system, once the RWS system is installed you don’t even know it’s there, but your home and family are protected. Use the same installation kit as for the standard system, you just don’t need to drill as deep.
