With a standard Briton 376 two point locking push bar the maximum door size can be up to 1300mm wide & 2500mm high – anything smaller than this and you just cut the bar or shoot bolt tube down with a hacksaw while fitting. The standard Exidor 294 two point locking panic bolt will fit doors up to 1220mm wide & 2440mm high, but it your door is even bigger than this, then oversize extras can be purchased as upgrades to the kit: push bars and/or top shoot tubes are available at 1600mm long and at 2100mm long. This means Exidor panic hardware can cater for whopping door leaves up to a maximum 2150mm wide & 3180mm tall.
