SPEED RAM BOLLARDS - FOR HIGH ACTIVITY PARKING LOT CONTROL
Our new Speed Ram Bollards are a high security adjunct or alternative to conventional access control gates. Speed Rams extend or retract in 2 to 4 seconds, delivering quality customer service. Speed Ram Bollards, perfect for high volume operations, will effectively handle thousands of cycles per day. Placed in front of a swing arm gate, they eliminate the cost, aggravation, and security risk of broken gate arms. Speed Rams are designed to reduce the security risk of car thieves driving stolen vehicles through your gates and off your lot. For some applications, the installation of Speed Rams may significantly reduce parking lot insurance premiums.
