What is the difference between an LCN CUSH arm, and an LCN EDA arm?

EDA ARM - The EDA arm is a heavy duty parallel arm mount.  The degree of door opening is determined by the template used for mounting. EDA arm closers can only be mounted as a Push Side parallel arm installation.

CUSH/CNS - The CUSH/CNS arm is a heavy duty parallel mount arm, with a built in stop, designed to stop the door and prevent it from being opened past a predetermined degree of open. The dead stop point is not adjustable, it is set by templating. CUSH arm closers can only be mounted as a Push Side parallel arm installation.

SCUSH/SCNS - The SCUSH/SCNS is a spring stop arm, it has more cushion at the stopping point than the dead stop CUSH/CNS arm and stops the door from being opened past a predetermined degree of open. The spring feature occurs 5° before the dead stop point. The spring stop point is not adjustable, it is set by templating. SCUSH arm closers can only be mounted as a Push Side parallel arm installation.
