Entry Blocker Plastic 12" - 32"

Entry Blocker consisting of plastic shield with four arms. Advantage of the plastic Entry Blocker is that the manhole is suitable as an escape route (to remove light violence). Suitable for: 150# 16"- 32" / 300# 14"- 28" / 600# 12"- 28" / 900# 12"- 26" (bolts max M20)

Avoid the red / white ribbon which a manhole that should not be used is removed. Or that the wind blows away the red / white ribbon. With the Entry Blocker manholes are inaccessible. But these could still be used for the aeration of the equipment / tank.
