The SWING ARM GATE (SAG) features a structural steel beam that opens horizontally for crash-rated vehicle security. Great for controlled access points with low to medium vehicle traffic, the manually operated SAG can secure multiple lanes of traffic or wide checkpoints up to 36 feet, or up to 32 feet with the electro-mechanical operated SAG. For longer spans or split traffic situations two single gates can be combined with a removable or fixed center receiver SuperPost to deter, deny, and delay threats.
