Hafele COMAGLIO 1712 Drop-Down Seal Recessed Aluminum 630mm Adjustable Stroke

Product Overview

The Hafele COMAGLIO 1712 drop-down seal is installed within an aluminum profile recessed into the bottom of door leaves. Used in commercial and residential buildings, this model provides both acoustic insulation and smoke sealing for interior doors, helping projects comply with sound and safety requirements. The unit suits OEM, refurbishment, and new construction scenarios where door bottom sealing must be concealed.

A standout feature of this SKU is its adjustable stroke and angle mechanism, accommodating doors with uneven floors or irregular installation tolerances.

It is particularly well-suited for contractors and door manufacturers handling renovation projects or bulk installations with varying on-site conditions.
