If the requirement is to cordon off a parking lot or entrance to a housing estate where a manned guard is always present, then the CENTINEL manual traffic barrier is a perfect cost-effective answer. The CENTINEL is available with 3, 4.5 and 6 metre boom pole lengths.
Using an internal spring the CENTINEL avoids the use of unsightly weights to counterbalance the boom pole. This results in a particularly compact and aesthetically pleasing barrier befitting the entrance to any up-market installation.
When we designed the CENTINEL manual traffic barrier, we had the user in mind. After all, just because it's a manual traffic barrier doesn't mean that you have to do all of the work!
