Increase productivity and profitability

GridMarX increases productivity and profitability every step of the way. When fastening for code, the guide marks help to quickly identify nail/screw patterns, virtually eliminating the need to measure between fasteners. Plus, cleaner nail/screw patterns provide a visual benefit for inspectors, which makes inspections much faster and smoother. Contractors save time and money every step of the way.


With GridMarX, guide marks run the machine direction of the board at five points in four-inch increments so the installer always has a reference point. Marks run along the edge in both tapers and at 16", 24" and 32". The marks cover easily with no bleed-through using standard paint products.


Features and benefits:

  • Vertical Application - In a vertical application, GridMarX serve as a guide mark to help identify the exact location of framing members behind the gypsum board eliminating the need for field applied vertical lines.
  • Horizontal Application - In a horizontal application, GridMarX serve as a reference mark to help identify the location of framing members behind the gypsum board. For example if the framing member is located 2 inches to the right of the GridMarX reference mark at the top edge of the board, it will be located 2 inches to the right down the face of the board.
