Door Dampers

The safe way to close doors

Energy capacity 190 Nm/cycle
Stroke 120 mm

Safety for individuals, doors and frames: whether acting single-sided or double-sided, ACE TD-28 and TDE-28 dampers securely prevent doors of all types and many weight classes from slamming shut. This is because the energy for stroke lengths between 50 mm and 120 mm is absorbed so reliably, that people and their possessions are protected.

The desired attenuation force is set manually; as a result, this door damper can absorb energy up to max. 190 Nm/stroke. Impact masses up to a maximum of 7,000 kg can be overcome depending on which type. ACE door dampers are manufactured to be high quality and durable with hard chrome-plated piston rod and galvanised steel cylinder tubes.
