Tumbler Roadlocks / Roadlocks

Tumbler Roadlocks

In some public places such as a construction site, the roadblocks can remind
us of a possible danger. However, sometimes the roadblock may be blown away
by strong wind. Once removed from its original place, it might lose the function
of indicating. As a consequence, an accident is very likely to occur.
The Tumbler Roadblock was designed to cope with the problem. The bottom
of the Tumbler Roadblock is made of rubber so that it can stand stably just like a
tumbler and permanently give indications to the pedestrians and vehicles passing
