To reinstate acceptable fire protection for old meter boxes, Ritherdon developed and tested the FireSeal – a fire and smoke resistant meter box door and frame unit.
The FireSeal is a modified version of the existing Ritherdon meter box door and frame repair units that incorporate multiple fire-resistant design elements, including steel construction, high temperature resistant locks, extra door strength and can be fitted to a wall to cover a variety of aperture shapes and sizes.
It is designed so that during a significant fire in a building, it will provide at least 60 minutes* mechanical protection (i.e. hold back the flames) and also prevent the transmission of smoke and harmful fumes through any aperture that the unit covers (it could be covering a meter box, an aperture or junction box).
