DORMA 7400 Series Door Closers – Flexible, Reliable Door Control in Minutes
The 7400 Series door closers from DORMA come with a ton of different options to meet a range of unique needs. For example, the 7414 door closer has spring sizes ranging from 1 to 4, which meets the 5 lb interior barrier-free requirements. (For 8.5 lb or less on exterior doors without the closer attached, you’ll require 1lb or less of opening force.) For something a bit heavier, try the 7436 with spring sizes ranging from 3 to 6. And both closers are available in aluminum, bronze, gold and black as well as custom and designer colours. You simply need to let Reflect Window & Door know what you need when you order.
With the 7400 Series, you can have delayed action for a maximum opening of approximately 65%. Each comes with a selective single point hold open that ranges from 80 to 170 degrees for regular mount or 70 to 175 degrees for parallel arm mount applications. You can choose between sex nuts and machine screws for a 3/4″ or 3/8″ door. They can also be ordered with self-tapping screws for aluminum applications, self-drilling screws for metal applications, or TORX security fasteners for situations where you need added security.
