Protect facilities from vehicles with retractable bollards
Bollards stop moving vehicles from ramming into public facilities or strategic sites. Ideal for providing perimeter security and controlling access points to roads. Consist of short posts, set at intervals, which withstand impact of a 7-ton truck traveling at 30 m.p.h. Automatic style retracts into ground in less than 5 secs. via remote-control devices (such as keypads) to clear the way for traffic. Bollard then automatically rises once vehicle passes. Also available in mechanical version, by which a person turns a key to unlock mechanism, then manually steps down on bollards head to lower post. Just turn key again to elevate and lock bollard in upward position. Select from a range of sizes, which stand up to 35 ins. high (above ground level). Requires minimal space below ground. Each post includes 2 impact-resistant cover pieces, held in place by jacketed assembly, along with steel wall measuring up to 0.8 in. thick. Current installations include the Pentagon and embassies around the world.
