Bottom slat

The bottom slat is the last slat of the shutter, the one at the bottom that rests on the sill or the floor when the shutter is down. It is usually thicker or stiffer than the others and carries the stops that keep the shutter from disappearing completely into the box.

It is the only one that can be gripped from outside, and that is why it is the weak point of any shutter. From there, people try to lift the curtain or bend the slat to pull it out of the guide rails.

In our shutter security system we work on exactly that point: we bond and screw a 4 mm steel T-profile under the bottom slat, which does not bend, and fit bolts at both ends that lock into the wall.
