Abstract: A drop down seal is provided which has a channel-shaped external support profile configured to be fixed to a base of a panel of a door or window, a rod-shaped support element slidably housed in the channel-shaped external support profile and a movable element connected to the rod-shaped support element by a parallelogram articulation mechanism allowing the movable element to move in height between a raised rest position and a lowered working position. The movable element, when in the raised rest position, is also operationally and removably connected to the channel-shaped external support profile. The rod-shaped support element, at a proximal end thereof, forms, or is provided with, a laterally protruding control portion configured to be engaged by a trigger base fixed to an abutment surface.
