The Gridlock© Manhole Protection System offers a fast and safe way to cover manholes whilst allowing visibility and limited access for things like gas detector checks, venting, CCTV and some jetting procedures.
The Gridlock© comes in a transit bag complete with everything you need for instant protection.
The frame itself is HI Viz and lightweight, cantilevering open until it hits its engineered stops. A leash is then connected and the frame is lowered so that Gridlock© ends up over the open manhole and also offers protection during placement in case of a fall. Once sited, the push on restriction clips are fitted so that the Gridlock© frame cannot be kicked out of position.
The Gridlock© is also ideal in training situations to ensure that trainees cannot fall into the manhole but can perform visual inspections and checks in total safety.
This Gridlock© is 900mm, suitabe for regular 600 chamber openings.
Alternative sizes available to order: 1200mm and 1500mm.
