Zero Dropseals
Zero dropseals are fitted to the bottom of the door and automatically drop down each time the door is closed (adjustable drop up to 25mm on most patterns). The mechanical unit requires no electrical power to operate, and works on a hinge side plunger with flat spring mechanism that drops the neoprene gasket in a scissor like motion for a tight seal without any drag, even on an uneven floor. As the neoprene seal compresses, it forms a tight secure bond against the threshold or floor. The door seal retracts automatically when the door is opened.
All ZERO automatic door bottoms function the same way. The mechanism causes the insert seal to activate on the hinge side first. It prevents the seal from dragging along the floor or threshold while the door is being closed to avoid door hang-up or closing delay.
