Installing a Storm Door

1
TEMPORARILY SECURE RAIN CAP

Install the rain cap with a screw if the manufacturer’s instructions recommend installing it before proceeding with the door installation.

2
POSITION THE HINGE-SIDE Z-BAR

Most doors are made so you can hang them with the hinges on either side using the same Z-bar. Put the Z-bar against the opening on the hinge side and mark the top with tape.

3
MEASURE OPENING HEIGHT AND CUT HINGE-SIDE Z-BAR
  • Draw a cutoff line this distance from the underside of the top of the Z-bar.
  • If the sill slants, follow the manufacturer’s directions.
  • Cut along the line with a hack saw.
4
PLACE THE DOOR IN OPENING AND SECURE WITH SCREWS
  • With the exterior door closed, place the storm door in the opening and push the hinge side up against the jam.
  • Make sure it is plumb and level.
  • Open the storm door and add the remaining screws to secure the hinge-side Z-bar.
5
ADJUST TOP Z-BAR AND SECURE WITH SCREWS
  • Secure the top Z-bar with screws provided with a ¼-inch gap between the bar and the door.
  • Check with a level to make sure it is plumb and check to make sure the door opens and closes freely.
  • Make any necessary adjustments and add the remaining screws.
6
MEASURE LATCH SIDE OF DOOR AND CUT Z-BAR
  • Measure from the bottom of the rain cap to the top of the sill on the latch side of the door.
  • Mark the measurement on the side Z-bar and cut with a hack saw.
  • Make sure you adjust the cut to match the slope of the sill.
7
POSITION THE HANDLE-SIDE Z-BAR AND SECURE WITH SCREWS
  • Cut hinge-side Z-bar as in Step 3.
  • Place it in the opening, tight against the rain cap. Adjust it so there’s a ¼-inch gap between the bar and the door’s edge.
  • Screw it in place.
8
INSTALL THE HANDLE SET, EXPANDER SWEEP AND DOOR CLOSER
  • Install the handle set and associated hardware.
  • Slide the expander off the bottom of the door and install the sweep.
  • Position the sweep so its weather stripping touches the sill and screw into place.
  • Complete the installation by installing the door closer. Loosen or tighten as necessary.
