The 1 5/8" roll-bar style tubular frame will be made of .134" (10 gauge) hydraulic tubing and formed with six (6) bends to allow maximum officer protection against side impact and vehicle roll-over accidents. The tubular frame is constructed with three welded mounting tabs per side of 12 gauge steel to allow the installation in most vehicles to be a NO HOLES DRILLED & NO TRIM CUT process and all partitions include wing/filler panels to close off access to the front seat area.
