94063 FRP Manhole Cover
The Shand & Jurs 94063 FRP (Fiberglass Reinforced Plastic) Series Manhole Cover is designed to provide emergency venting relief of low-pressure storage tanks and vessels. These covers also provide quick, easy access for tank inspection and maintenance. When the tank is exposed to abnormal internal pressure beyond the capability of the conservation vent, the manhole protects the tank against costly rupture.
