Woodland Scenics ST1409 Sub Terrain 4in Riser
This package includes two 4"x24" Risers that are used for dramatic, steep relief on your layout, and to create lower areas for rivers and valleys. Risers are easily flexed to form curves and can be used on plywood or a foam base. To install, butt the sections tightly, pin in place with Foam Nails (ST1432) and attach. The Low Temp Foam Glue Gun (ST1445, and Glue Sticks ST1446) is the fastest way to assemble your foam base, but you can also use Foam Tack Glue (ST1444).
