Owing to their outstanding practical features and characteristics, DORMA door closer with projecting arm assembly are popular for use in hospitals, sheltered housing, hotels, public houses, bars, restaurants and office buildings.
If more time is required for passage through the doorway, the optional delayed-action mechanism provides this very feature – also applicable on fire and smoke check doors. The DORMA TS 83 is provided as standard with adjustable, self-regulating backcheck. Hold-open arms with on/off selector are also available for temporarily holding the doors at a specific point. And for external doors, the DORMA TS 83 can also be supplied with optimized corrosion protection.
