GEZE TS 500 NV Floor Spring Door Closer Concealed EN 1-4 90° Hold-Open 150kg

Product Overview

GEZE TS 500 NV is a concealed floor spring door closer designed for internal swing doors, compatible with both left- and right-handed installations. Mounted within the floor with a 42 mm installation height, it supports doors up to 1100 mm wide and 150 kg leaf weight, and meets EN 1-4 closing force compliance per PN EN 1154. Hermetically sealed zinc-coated body and safety valve provide robust performance in high-traffic commercial and institutional spaces.

The integrated 90° hold-open function distinguishes this SKU, allowing doors to remain securely open at a preset angle until manually released. This simplifies compliance with accessibility and operational requirements in environments where temporary passage or barrier-free access is needed, such as hotels, retail, and office buildings. Particularly recommended for bulk procurement in commercial construction or retrofit projects requiring hidden floor closers with selective hold-open capability.
