he Fontaine-Aquanox SERIES 61 at the outlet. Inlet flap gates are often used in cold climates or simply when space does not permit a standard flap gate. The gate is mounted inside a square or round manhole on the concrete wall . The front panel is removable for easy access to the flap. A self-lubricating UHMWPE bushing in the hinges prevents metal-to-metal contact thereby reducing friction and easing the operation. Even if the gate is not used for a long period of time, there is no risk that the hinges will rust or seize.

The adjustable hinges on flap gates 30" (762 mm) and over (Figure 61-02) help control the sensitivity of the flap to open.

The frame can be manufactured to be mounted on any installation. Figures 61-03 through 61-06 show different types of mounting.
