Top Sign Letter Track for Changeable Letters

Create a customizable sign with lettering by ordering the top track and bottom track, in addition to the necessary middle dual tracks needed for the desired amount of text lines. This rigid track is suitable for use with rigid changeable sign letters.

Track Installation Instructions


Rigid track is exclusively designed for Rigid letters and not compatible with Flexible letters. To identify Rigid letters, look for the brand name "GEMINI" printed beneath each letter.

Length Sizes: 

Rigid Track is available in 6", 8' and 10' length.

Installation on Expanding Background Materials | Plastic | PVC

If the surface you are attaching the Pronto Track onto will expand and contract at somewhat the same rate as the plastic track, installation can be done using either rivets or adhesive. Using a chalk line and level, mark the location for your first piece of track. Track can be installed with Pronto Track Rivets or with adhesive installation such as Weld-On #3 or #4.

  • For a rivet installation: drill a hole through the track and background (maximum 8" center to center). To fasten track to 1/8"- 3/16" background, drill .1875 diameter hole (3/16" drill bit). Insert the Pronto rivet, then push the pin to its closed position.
  • For an adhesive installation: Using a syringe or bottle applicator with a thin needle tip, apply a steady line of adhesive, such as WELD-ON #3 or #4, to the back face of the track. Tape in place until adhesive has set up completely

Installation on Non-Expanding Background Materials | Wood | Metal

If the surface you are attaching Pronto Track onto will not expand or contract (ie. wood or metal) at the same rate as the plastic track, we recommend the following installation procedure:

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

See Letter Track Spacing Chart below

Accurate spacing is the key to a good changeable letter system. Refer to the Track spacing chart shown below to determine the total height of your sign. The use of dual middle track automatically spaces the rows and reduces the number of track pieces required. If row spacing needs to be greater use a combination of top and bottom tracks.
