ROXTEC ARW0000601018 60mm Glavanized Steel Wedge. Highly efficient compression unit, which saves valuable installation time both when it comes to installation and re-installation of the Roxtec sealing system. The complete compression unit consists of only one piece which, by turning the screws in the front, both compresses and decompresses the wedge. Used in frames with a rectangular packing space without built-in compression. Compresses and seals the installation of cables, pipes, modules and stayplates.
