If the track mis-cut is too long, take several measurements to ensure the correct value, then trim or file the track as required to the correct length. Reinstall per instructions. If a bottom track mis-cut is too short by less than 1/4", then apply caulk to the gap created. If the track mis-cut is too short by more than 1/4", you can purchase a replacement directly from us.
