Remove the bracket that is attached to the storm door.

Lay out the placement of the new brackets.
The template for new brackets can be found in the instruction manuals given with the new hardware. Be sure to pay attention to the type of door it is being installed on.

Use the cordless drill to attach the smaller bracket to the storm door.
Ensure screws are tight but not overtighten to the point the screw head is ruined by the over-torque (otherwise known as being "stripped").

Depress the plunger.
Open the door as wide as the piston will allow you to.
