Pemko 412SRL36 Automatic Door Bottom Sweep 36 Inches

Product Description

The PEMKO 412SRL36 is an automatic door bottom sweep designed to seal the gap between the bottom of a door and the threshold. When the door closes, the internal mechanism drops the sweep into contact with the floor surface, blocking drafts, dust, light, sound, and moisture. The drop seal uses a sponge neoprene insert that compresses against the floor for consistent contact. The housing is stainless steel coated for corrosion resistance. At 36 inches in overall length and 1-15/16 inches in height, this unit fits standard interior and exterior door applications. Installation is performed by door hardware professionals, carpenters, or general contractors.

The 412SRL36 is suited for commercial and residential door applications where a reliable automatic bottom seal is required. Typical installations include office entries, hotel corridors, apartment unit doors, and any door location where controlling sound, smoke, or environmental infiltration is a priority. The sponge neoprene insert provides a compliant seal surface that accommodates minor floor irregularities without requiring precise threshold height adjustment.

Key Features

• Automatic drop mechanism seals door bottom on contact with latch strike
• Sponge neoprene insert compresses for consistent floor contact across minor surface variations
• Stainless steel coated housing resists corrosion in high-traffic or humid environments
• 36-inch length fits standard door widths
• 1-15/16 inch height profile keeps the sweep low-profile on the door face

Compatibility

Designed as an OEM-style drop-in replacement or new installation automatic door bottom sweep for standard 36-inch commercial and residential doors where neoprene seal inserts are specified.

Installation Notes

Installation is typically performed by a door hardware technician or finish carpenter. The sweep mounts to the interior face of the door using the provided housing and fasteners. Verify door thickness and bottom clearance before mounting to ensure the neoprene insert contacts the floor surface properly when deployed. Confirm the actuator pin aligns correctly with the door stop or strike to trigger the drop mechanism on close.
