GEZE TS 4000 TANDEM EN7 Door Closer Articulated Arm Silver for Wide Heavy Doors

Product Overview

The GEZE TS 4000 TANDEM EN7 is a tandem door closer system with articulated arm designed for extremely wide and heavy doors, such as those found in commercial and industrial environments. This dual-closer setup delivers certified closing force for doors from 1600 mm width upwards, making it suitable for fire-rated and smoke-control doors in high-traffic facilities. Hydraulically regulated opening damping and optical force indicator ensure compliance and installation control for demanding projects.

What sets the TS 4000 TANDEM apart is its dual mechanism, combining TS 4000 EN5-7 and TS 4000 EN1-6 closers for double power and continuous force tuning from EN7. This configuration eliminates the risk of insufficient closing pressure and failure to secure heavy or oversized doors, which is critical in fire safety and access control installations. It is recommended for specifiers and bulk buyers handling large door assemblies in commercial complexes, logistic centres, or public infrastructure projects.
