Floodgate Door Barrier covers in various weights, depending on what model you go for. There is a jacking mechanism attached to the back of the frame which allows the frame and cover to both expand telescopically width ways into the walling area, in front of the door. There are four bolts along the bottom edge of the frame, which are adjusted to give a seal along the ground.
Floodgate Door Barrier is a great design, requiring no permanent fitting or requiring pre-drilling of the door frame .This product is perfect to be used on old and listed buildings. All Floodgates are 68cm (2'3") high. Research has been done and for any above this level the water pressure on the outer walls can cause structural damage. This Floodgate provides more protection than 50 sandbags and weighs less!
