Highway D400 HaloHinge

A Hinge and life out expansion of the highway range, allowing the manhole covers to be safely removed using our unique safety keyways and standard BS 7903 lifting keys but can also be hinged to 100 degrees where they are secured in place.

Highway D400 halo hinge

HaloHinge's innovative design incorporates inboard hinges (on the inside of the frame), this allows easy surfacing compaction against the straight edges of the frame. This is unlike common alternatives, which have protruding hinges that are difficult to compact around without running the compaction equipment over the hinge housings, which applies destructive forces to the hinge housing and covers foundation.

The inboard hinges also provide the added benefit of preventing hinge pockets from becoming clogged with dirt and debris, this ensures the hinges will reliably operate and promotes improved health and safety.

Highway HaloHinge covers are also compatible for GritBlocker, ensure safe operation, first time, every time
