Improved ergonomics: Hinges reduce the physical effort by 50%.
Hinges allow operator to move in a straight line, thereby avoiding damaging spinal rotation.
Hinges minimize the duration of the lift; the hinge also retains the cover in a safe and controlled way during and after the lift.
Hinge incorporates a 90º blocking feature to prevent accidental closure.
Self-centering design of the gasket eliminates the need to guide the cover into position when closing.
Design of apertures ensures easy insertion and removal of tools.
Lifting loops in the frame facilitate safe offloading and installation with the proper equipment.
The cover is designed to open and release pressure if the sewer becomes surcharged.
The cover can be removed if necessary.
