1712 Drop Seal Threshold Gasket US-HF-004 Aluminum 1130mm Dual Adjustable Extension

Product Overview

The 1712 Drop Seal Threshold Gasket (US-HF-004) is a floor-mounted sealing system designed for use in wooden or PVC doors, including soundproof, smoke-control, and fire-rated installations. It features a 1130 mm aluminum body with a black silicone sealing profile, and is installed via mortising into a pre-cut groove (12x28.5 mm), suitable for professional and commercial environments requiring effective door bottom sealing.

What sets this model apart is its dual adjustment mechanism for both extension length and angle of the seal, enabling precise adaptation to varied floor conditions and ensuring consistent sealing performance. This feature helps minimize installation risks associated with uneven surfaces and is ideal for procurement where doors face differing installation requirements, such as in hotels, office buildings, and public institutions.
