Pronto Changeable Letter Track Installation

1. Drill or route horizontal oblong or oversized holes in the track as in the illustration below.
2. Using a sheet metal screw, because of its squared shoulder; put the screw in the center of the horizontal hole.	3. Do not tighten the screw. Leave it approximately 1/4 to 1/2 turn loose.	4. When all the screws are in the track you should be able to wiggle horizontally a small distance.	5. Now the track is able to expand or contract with temperture changes, and shouldn't buckle or warp.
