Tip: The Hoffman Key has a rounded and a flat side to it. The rounded side goes in face up.

Repeat step 3 for remaining corners to complete the 4 sided frame assembly.

If not installing with T-POST skip to Step 5.

4. Locate and identify the top and bottom labeled t-post. Line up the pre-drilled holes with the top and bottom frame and secure with screws provided.

Tip: It is best to angle the drill gun or nail gun to ensure contact with a stud around the window opening.

7. Once the left side is secured, level the frame on the window and secure with nail/screw (pre-drill) into the upper right frame. Shutter will be fully secured in later steps.

Once top right & left frame are secured, panel can be installed.

Note: If installing 2 panels, insert left panel first, then right panel.

9. Once panel has been positioned and secured with the hinge pins, make sure shutter panel is even across the top and bottom. If panel is not even, shift (rack) your frame left to right until your reveal is even.

Remember, the bottom frame should not be secured at this point.


10. Once your panel has been shifted (racked) and with the panel in its closed position, mark the bottom left side of the wall along the side of your frame. Open the panel and position your frame in reference with your mark and secure a nail/screw (pre-drill) to the bottom of the left frame below the hinge and tighten.

TIP: With the bottom right secured, step away from the window and open louvers to make sure shutter is evenly positioned to window.

Things to look for: Align window mullions and/or sectioned glass with shutter lines (louver, stiles).

11. After securing the bottom left, secure nail/screw (pre-drill) at the bottom right below the hinge and tighten.

13. Now that you have secured the top and bottom corners and your panel operates properly, secure with nail/screw (pre-drill) the middle of the bottom, top and side frames.

Make sure the gap between the panel and the frame are even.

Tip: Move top and bottom frames up and down to achieve proper tolerance between panel and frame. Tip: Move side frame in and out to achieve proper tolerance between panel and frame.

14. Make sure shutters operate properly. Add additional nail/screws (pre-drill) (if needed).
