Incline Starters are wedges of high-density foam used to start your track on an incline or decline. Each piece in a package elevates/lowers the track to/from a designated number of inches within a 24 inch stretch, allowing for a smooth transition from one height to another. To install, pin in place with Foam Nails and attach with Foam Tack Glue™ or the Low Temp Foam Glue Gun and Glue Sticks. Use alone or with Risers.
