DuraHold, a massive wall unit for massive walls.

The large size of Dura-Hold makes it an excellent choice for demanding structures up to 40ft (12.19m). Proper engineering and a good selection of components make this an exceptional wall system. It’s a great alternative to “poured” in place concrete.
