The Defender security bollard is K4 certified by the U.S. Department of State, meaning it's capable of stopping a 15,000 lb medium-duty truck traveling at 30 mph. The Defender bollards are made of retractable, 10 3/4" diameter, round tubular columns with a full guard height of 30".
The Defender anti-ram retractable bollards, available in automatic or manual, are excellent for sites where the pathway access changes often. When retracted, the Defender security bollards are flush with the roadway and provide free movement of pedestrians and vehicle traffic.
Utilizing the highest cycle duties available, the Defender automatic hydraulic rising bollards are an economical and effective way of securing any access point.
The Defender fixed security bollards provide safety and protection to key assets, yet do not restrict the freedom of pedestrians.
For sites where around-the-clock protection is a must, choose Ameristar's Defender fixed security bollards.
The Defender removable bollards are designed for areas where frequent and fast manual removal of the bollard may be necessary.
To remove, simply unlock these bollards using the internal locking mechanism and then lift using the hidden lifting lug.
