Creating End Caps for 5" Lineals
To create the header, first cut a 7" piece of 5" lineal. Measure
and trim as shown.
The resulting piece fits into the end of the 5" lineal.
The ends of the 5" lineal also need trimming to receive the end
caps. Create a 3/4" rain tab in the pocket area and trim off a
3/4" tab from the bottom.
NOTE: To make end caps for 3-1/2" lineals, simply start
with a 5-1/2" piece and remove the 3/4" and 2" areas as
shown for the 5" end caps.
