PLYLOX Installation
- Measure each window casing
- Record each measurement on this convenient
chart.
- Work left-to-right, floor-by-floor.
- The recorded height should be the measured height from top to
bottom of the casing minus 1/4". The recorded width should be the measured
width from side to side of the casing minus 1/4". This will give 1/8" clearance
all the way around.

- Cut 1/2" plywood to the recorded size of each window.
- Mark each cut piece with its label, such as FF1, the window at
the left front of the house on the first floor.
- If you keep the chart and
label the plywood covers, you won't need to label the casings.
- Place the PLYLOX clips on each plywood cover (if the window
is 24"x24" or smaller, only two PLYLOX clips are needed).
- Each clip should be placed on the edge of the plywood cover no
more than 24 inches apart.
- Make sure the tension legs are facing towards you.
- Push the plywood covers with the PLYLOX tension legs to the
outside firmly into the casing.
- PLYLOX works as well in round windows as they do in
rectangular windows. You can adjust the number of PLYLOX clips used to
account for different shapes and sizes of windows.
