Tough Stuff

military grade material

Rumber® is a truly remarkable product. This is a military grade material. And we mean that literally. We are currently selling to the U.S. Army for it’s grenade training ranges. Previously they had a plywood wall along the trench to keep shrapnel from flying back at the soldiers. Each day they had to rebuild 1000′ of wall. They’ve been throwing grenades at a Rumber wall for over a year now without failure. This is TOUGH STUFF.

Basically it is available in two forms:

1. Extruded lumber profiles of S4S and T&G in 2×4, 2×6 and 2×8. Colors are black, gray and brown. Smooth and high traction (buffed) surfaces.
