Octa / Innovative Manhole Cover


Octa is an innovative manhole cover which adopts an octagon folding structure. It allows the manhole cover to transform into an alarming sign while it open. This design makes it easy for people and vehicles to notice, and the barrier structure effectively prevents pedestrians from falling into the manhole.
