There are 12 Strips in this Track-Bed Standard Pack. These strips are the perfect roadbed for especially tight track applications. The Strips are 5mm x 1 3/4" x 24". Track-Bed requires no pre-soaking like cork does: it remains flexible and won't dry out or sbecome brittle! It aligns well with cork or Homasote applications. Install Track-Bed with Foam Tack Glue (ST1444). Pin in place with Foam Nails (ST1432).
