Aluminum Drop-Down Threshold Seal 725x15x44mm Adjustable 7mm Gasket Grey Trimtable

Product Overview

The Listwa progowa 725x15x44 mm is an automatic drop-down threshold seal made from aluminum, designed for installation at the base of doors. It provides effective protection against air, smoke, dust, and noise, making it suitable for both residential and commercial environments where enhanced sealing is required. The seal includes a grey gasket and supports a maximum extension of 7 mm, accommodating installation variances and floor unevenness.

A distinguishing feature of this model is its ability to be shortened by 10 cm without compromising its sealing efficiency or structural integrity. This adjustability reduces procurement risk for B2B buyers by allowing a single SKU to fit various door widths within project portfolios, minimizing inventory complexity. It is particularly suitable for contractors and door manufacturers seeking flexibility across multiple installation scenarios.
