Pemko 420APKL Hollow Metal Automatic Door Bottom with PemkoPrene Insert
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.
