Glue Fixing

If weld or screw fixing to the steel surface is not an option, the GMXP0 mounting plate can be secured
by glue fixing to a clean area of the protected surface. For improved adhesion results the surface of
the protected surface should be scratched with a form of abrasive material or tool. The recommended
option for installation is to drill or weld the GMXP0 to the protected surface and to follow the installa-
tion guides throughout this document and the associated installation sheets.
