Zenith Concealed Automatic Drop Down Door Seals – ADDS-A
Engineered for superior sealing performance, the Zenith Concealed Automatic Drop Down Door Seal offers a discreet, high-efficiency solution for controlling noise, dust, drafts, light, and smoke infiltration. Designed to fit seamlessly into the bottom of timber, steel, or aluminum doors, its concealed profile maintains a clean, modern appearance while delivering outstanding functionality.
When the door closes, the precision spring-loaded mechanism automatically lowers the seal, creating a tight barrier against the floor or threshold. Upon opening, the seal retracts silently, ensuring smooth operation and long-term reliability.

Concealed Design – Hidden installation preserves door aesthetics
Automatic Operation – Lowers on closing, retracts on opening
Premium Build – High-grade aluminum body with durable silicone sealing gasket
Excellent Sealing – Protects against sound, drafts, dust, smoke, and light leakage
Versatile Application – Ideal for acoustic, fire-rated, and energy-efficient doors
Easy Installation – Includes end plates and fixing screws for precise fitting
Applications:
Perfect for hotels, offices, hospitals, residential units, and public buildings requiring superior acoustic control, energy efficiency, and smoke containment.
Sizes Available: Multiple lengths (can be trimmed to fit)
Finish: Silver anodized aluminum or custom colors on request
