    Automatic Door Bottoms utilize a concealed flat spring mechanism and plunger. When the door is closed, a brass plunger is compressed to automatically lower the seal, starting from the hinge side first. This motion ensures a smooth usage even on an uneven surface and prevents drag. The seal is automatically raised upon opening. These automatic door bottoms have been successfully tested through 5 million cycles!

    Comments about Zero #350, Automatic Door Bottom, Mortised with Neoprene Seal, .75" Drop

    We bought a 13" unit, we must have done something wrong when adjusting it... Two weeks in service, the unit broke and had to get replaced. We also didn't like the neoprene seal, it felt too simple. #sweepstakes I definitely would but this product but for doors that'll see less traffic. PSM Construction Services, SoCal
