The Grab Box of 240 Mixed Broadfix Flat Packers have been manufactured with a high percentage of post-industrial and post-consumer recycled material. As they are made from plastic they will not swell, shrink or rot and they are completely waterproof. The packers are capable of withstanding higher compressive loads than traditional timber flat packers, this also makes them more economical. They are colour coded depending on size, for easy identification. Specifications: Size: 100 x 28mm.
