Now supplied with our improved Gridlock Locks© in place of the restriction clips.
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 or venting procedures.
The Gridlock© comes in a transit bag complete with everything you need for instant protection.
The frame itself is lightweight and cantilevers 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 Gridlock Locks© 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 set is suitable for manholes up to 600mm.
