StopGap gap fillers are used to fill in the electrical isolation gaps for the frog.
A StopGap is inserted into each isolation gap, cut into your completed turnout, and then glued into place. The filler is long enough to sit on the roadbed, reducing any possibility of the filler working its way loose over time.
Each sheet includes 36 StopGaps for rail sizes code 70 and up.

Another little detail which helps building better looking tracks. After cutting a track with a small grinding wheel, it fits exactly in the gap.
