Additionally, the 104FG provides a convenient finger grip feature on the cover to facilitate cover removal.

At a fraction of the weight of typical steel manholes, FLEX-ING™ brand composite manholes give you all the benefits of a solid, well-constructed manhole with none of the difficulties you've come to expect from steel. A single technician can easily remove the lightweight cover while the composite construction and design allow the cover to stand up to the harshest forecourt conditions.

• Constructed of many layers of high quality fiberglass bonded together with premium resin and then handfinished with the utmost attention to quality.
• At their center, our manholes tapper up from 1" to 1-�" in wall thickness while most competitive models remain at a uniform 1" wall thickness. This extra wall thickness provides minimal deflection and an extended service life.
• A shallow handle hole and chest-style handle with backer plate keep the wall thickness higher around this high-impact area of the cover.
