Drop Seal US-HF-006 1712 Aluminum 1330mm Double Adjustable 44dB Recessed Door Seal

Product Overview

The threshold drop seal 1712 alu. DL 1330 mm (US-HF-006) is designed for installation in wooden or PVC doors, including those requiring acoustic, smoke, or fire protection. Its casing is made from aluminum, while the sealing profile utilizes black silicone. The seal is fitted by being recessed into a pre-cut groove of 12x28.5 mm, supporting a maximum sealing height of 18 mm and offering an acoustic isolation rating of 44dB for a 6mm gap.

What sets this drop seal apart is the double adjustment feature, enabling precise control of both the projection length and angle of the seal. This adjustment capability is especially valuable for installers facing irregular door gaps or non-uniform floor surfaces, reducing potential fitting issues and post-installation tweaking. It is particularly suited for projects requiring certified acoustic, smoke, or fire protection in commercial and residential construction.
