Pemko 4131DRL Fire-Rated Automatic Door Bottom | Dark Bronze Finish
The Pemko 4131DRL Fire-Rated Automatic Door Bottom is a premium, architectural-grade solution designed for superior environmental control and fire safety. Featuring a sophisticated Dark Bronze Anodized Aluminum finish, this versatile unit is engineered for either surface-applied or semi-mortise installation. This flexibility makes it the ideal choice for retrofitting existing doors in upscale condos, luxury hotels, and commercial offices where maintaining a high-end aesthetic is just as important as performance.
Equipped with a resilient Sponge Neoprene insert, the 4131 Series creates a slightly compressible, airtight seal that excels in extreme conditions. The "smoother action" positive seal mechanism is triggered by a jamb-contacting plunger, ensuring the seal only engages when the door is closed. This prevents seal skidding and ensures the door operates effortlessly while blocking drafts, sound, and smoke.
Key Features & Performance
- Surface or Semi-Mortise Mounting: Offers the versatility to be mounted to the face of the door or partially recessed, making it compatible with both wood and hollow metal doors.
- Sponge Neoprene Seal: A high-durability rubber insert that remains flexible at both high and low temperatures and resists deterioration from oily substances.
- Non-Handed Design: Completely reversible for fast and easy installation on any door handing without complex disassembly.
- Positive Seal Mechanism: The drop-bar is actuated from the hinge side, ensuring a level, consistent seal across gaps up to 3/4".
- Dark Bronze Anodized Finish: Provides a clean, symmetrical square-shaped case design that blends perfectly with dark hardware and architectural wood finishes.
