The SN 15x30 automatic drop down seal features an aluminum alloy body with an integrated silicone rubber insert, designed for mortise mounting at the bottom of swing doors. Its 15 mm width and 30 mm height profile, combined with a 21 mm dropout depth, create an effective barrier against acoustic transmission, smoke and drafts when the door is closed. The spring-loaded design ensures automatic deployment without manual adjustment.
Engineered for residential and commercial applications, this seal is particularly suited to fire-rated doors in hotels, offices and healthcare facilities. The aluminum construction provides durability against heavy wear, while the silicone insert maintains flexibility in varying temperatures. Standard lengths from 230 mm to 1430 mm accommodate most door sizes, with the option for custom cutting to meet specific project dimensions.
Building hardware distributors and contractors commonly specify the SN 15x30 for projects requiring consistent sealing performance across multiple installations. Its mortise-mounted design allows for easy retrofitting to existing doors, making it a practical choice for upgrading older buildings. The seal's ability to block noise, dust and insects while maintaining smooth door operation makes it a versatile solution for diverse environments.

Verify the SN 15x30's compatibility with your door's material and thickness before placing an order. Request technical drawings to confirm the mortise dimensions required for installation, as these may vary by door type. Test a sample seal on your specific door to ensure proper engagement and retraction of the spring mechanism.
Confirm bulk packaging options with Modern Sealing LLC, as the SN 15x30 is typically supplied in pre-cut lengths for efficient shipping. Discuss Incoterms early in the process, with DAP or FOB Minsk being common for Belarusian exports. Agree on payment terms and lead times for both standard and custom lengths to avoid delays.
Inspect incoming shipments for consistent aluminum alloy finish and uniform silicone gasket thickness. Check the spring mechanism's tension on a sample unit to ensure reliable operation. Request documentation for the gasket's smoke resistance rating, and maintain records of all specifications for quality control and future reorders.
