Acoustical Door Astragal: #328 for use when both doors are active

Acoustical door astragals are designed to effectively seal off the air gaps that create sound leaks on double doors. One seal is attached to each leaf or door. The #328 is a neoprene seal to assure a proper closure. Just as you need acoustical door jambs to seal off the outside vertical sides and top of your door, these astragals are used to seal off the meeting point of the double doors.
