Hydraullically operated bollard system to protect entry ways to businesses or complexs. Ram proof. These can be raised or lowered at will. They can stay down during open hours and raised after hours to prevent entry or exiting of vehicles that are not authorized.
I have two brand new complete systems that I got a great deal on as part of an auction. Basically you can get a Sixty thousand dollar system consisting of 12 bollards and two separate control set ups for half that. These were never installed. They are new, old stock.
I have pictures and a real good description of the item. these were never installed and became available after the architect changed an approach to a building they were purchased for.
I don't have pictures of the actual style of the bollards that go with this system and I used "stock" pictures to give you an idea of what individual bollard styles are available.
copy and paste this to see a neat you tube video that shows how these protection systems work so incredibly well.
