Pemko 411ARL Full Mortise Automatic Door Bottom, Mill Finish Aluminum

• The nylon filaments conform extremely well to irregular surfaces such as carpet, stone and grout lines.
• Especially over uneven surfaces, both PemkoPrene^® (PK) and nylon brush (NB) provide excellent seals to keep out draft, dust, moisture, insects, fumes, light, and sound.
• Can be mounted to either wood or hollow metal doors.
• End plates are provided for all mounting applications.
• Seals up to a 3/4" gap under the door.
