5100 Series Sliding Doors All record-USA Series 5100 automatic sliding entrances allow the sliding doors to break away and swing in the direction of egress when force is applied. The doors can be pushed to swing at any point in the door opening or closing cycle (except for Reverse Breakout units), and the force required to break the doors away is mechanically adjustable. On units with exterior swing-out sidelights, breaking the doors away will also cause the sidelights to swing in the same direction as the sliding doors. These units also incorporate mechanical interlocks that lock the sliding doors and sidelights together when the doors are fully closed. record-USA utilizes 1 3⁄4” x 4 1⁄2” framing for the side jambs and transom members on all sliding entrances. Where applications require, optional 1” x 4 1⁄2” or 4 1⁄2” x 4 1⁄2“framing may be substituted. On telescope, full pocket, and surface mount units, 1 3⁄4 x 6 1⁄2” framing is standard with optional 1’ x 6 1⁄2” framing also available. On surface mounted units, 1 3⁄4” x 2 3⁄4”(narrow stile) or 1 3⁄4” x 4 1/4” (medium stile) filler tubes are mounted against the wall or storefront in place of sidelights to provide a weather seal and members to mount the safely beams.
