System and apparatus for filtering drainage which includes a configurable
and adjustable rigid frame, hanger support structures adapted to contact
a surface of a drainage structure, and a sediment bag. The frame may be
adjusted or configured by modifying the location of connecting fasteners
and/or by altering the orientation of frame components. Additional
embodiments provide for an overflow gap comprising a vertical distance
between an above grade surface of a drainage structure and the rigid
frame, wherein the overflow gap is capable of allowing runoff to bypass
the sediment bag when the sediment bag is obstructed. A configurable
lifting tool device adapted to lift inlet grates and inlet filter devices
includes a lifting bar, a plurality of connectors, a plurality of lifting
arms, and a plurality of lifting hooks adapted to contact a grate and/or
an inlet filter device lifting bar.
