Product Overview

The Uszczelka opadająca 1712 alu. DL 530 mm (US-HF-000) is a drop-down threshold seal designed for installation in wooden or PVC doors, including soundproof, smoke-control, and fire-rated assemblies. The outer case is made of aluminum, with a black silicone sealing profile, and fits a prepared groove of 12x28.5 mm. This product delivers 44 dB acoustic insulation with a 6 mm gap and can be used in commercial, institutional, and residential settings requiring enhanced door sealing.

A double adjustment mechanism for both seal projection and tilt angle distinguishes the 1712 model from standard drop-down seals. This allows installers to tailor the seal's performance to varying threshold gaps and uneven floors, minimizing fitment risk and guaranteeing reliable closure. Recommended for projects with diverse door specifications or renovation jobs where installation accuracy is critical.
