Pemko 420APKL Full Mortise Automatic Door Bottom for Hollow Metal Doors with PemkoPrene Insert Information
Pemko 420APKL Concealed Automatic Door Bottom
The 420 Series Full Mortise Automatic Door Bottom is specifically designed for hollow metal doors with a 13/16" inverted channel. It features a heavy-duty mechanism for smooth operation and is fitted with two fire-rated rubber seals. This door bottom prevents drafts, dust, moisture, smoke, fire, and sound from entering the gap under the door. It can be easily cut in the field for additional adjustment. The aluminum casing is fully mortised, maintaining the appearance of the door alleviating the need for end plates.
All sizes other than 36" are special order. Therefore once ordered they cannot be canceled, returned or exchanged.
Pemko automatic door bottoms consist of an aluminum case which surrounds a movable drop bar seal. The drop bar seal is actuated by a plunger which contacts the jamb as the door is closing, forcing the drop bar seal down against the floor or threshold.
