Can the Ideal Security Quick-Hold Storm Door Closer open to 90 degrees?

The answer is no. The Ideal Security Quick-Hold door closer can only swing open to approximately 70 degrees, this is due to the mechanism in the Quick-Hold feature.
In particular, the model 4015 will allow a opening of about 60 degree.
