Hercules™ D400 manhole covers

The double triangular covers are indexed to ensure correct orientation when fitting. The cover’s M16 blank bolt can be replaced with a threaded lifting eye for mechanical lifting – the position of the bolt is at centre of mass, allowing safe and level lifts.

The covers feature a small window allowing for easy and safe inspection without the need to remove the entire cover.

^Note

^{Additional M16 lifting points are present on Hercules cover sizes exceeding 1200×1200 Clear Opening in lieu of BS7903 Lifting Keyways, for alternative methods of mechanical cover lift. The Hercules 1,200 x 1,200 mm cover is the only cover in the range to have keyholes for manual lifting.}
