Grating fasteners secure removable steel bar grating to supporting structural members without welding or drilling through the support. For maintenance platforms, industrial walkways, mezzanines, and access areas, the correct clip helps hold the grating in place while preserving the ability to remove panels when service access is required.
The GFX-GG fasteners offered by Anchor Point Hardware are designed specifically for 19-space steel bar grating. Selecting the correct part requires two job measurements: the grating depth and the thickness or clearance of the supporting flange.
What does 19-space grating mean?
In this product family, 19-space refers to the bar grating configuration the clip is designed to fit. The top plate spans the appropriate bearing bars while the lower jaw reaches below the supporting flange. These clips should not be selected for a different grating spacing without confirming compatibility.
Before ordering, verify that the installed grating is 19-space steel bar grating. If the spacing is uncertain, take measurements at the jobsite or contact Anchor Point Hardware sales for assistance.
Step 1: Measure the grating depth
The letter at the end of each GFX-GG SKU identifies the grating depth. The sequence begins with A for 1-inch grating and increases in 1/4-inch increments:
| Depth letter | Grating depth | Example SKU |
|---|---|---|
| A | 1" | GFX-GG-1A |
| B | 1-1/4" | GFX-GG-1B |
| C | 1-1/2" | GFX-GG-1C |
| D | 1-3/4" | GFX-GG-1D |
| E | 2" | GFX-GG-1E |
| F | 2-1/4" | GFX-GG-1F |
| G | 2-1/2" | GFX-GG-1G |
Measure the full vertical depth of the bearing bar rather than estimating from the visible top surface. A depth mismatch can prevent the jaw from reaching the flange correctly or leave excess bolt length.
Step 2: Measure the structural flange
The number in the SKU identifies the jaw family. Anchor Point Hardware currently offers two jaw ranges: GFX-GG-1 for flange up to 21/32 inch, and GFX-GG-2 for flange over 21/32 inch and up to 1-11/32 inches.
Measure the flange where the lower jaw will engage. Confirm that paint buildup, galvanizing, edge conditions, or obstructions do not reduce the available clearance. The website's automatic clip selector combines this flange measurement with the grating depth to recommend an available SKU.
How to read a GFX-GG part number
Consider the SKU GFX-GG-2C. The "2" identifies the larger jaw family, while the "C" identifies 1-1/2-inch grating depth. A GFX-GG-1C fits the same grating depth but uses the smaller jaw family.
This naming system lets estimators and installers identify the required clip once those two measurements are known. The current product stock chart shows which combinations are included in the present catalog.
Installation considerations
GFX-GG fasteners are easily installed from above with a nut driver. The top plate sits above the grating while the lower jaw engages beneath the supporting flange. This above-grating access can be valuable where the underside of a platform is difficult to reach.
Before installation, confirm that the grating panel is properly positioned and supported. Place fasteners according to the project requirements, applicable engineering guidance, and site safety procedures. Tighten the fastener securely without deforming the grating or hardware. After installation, verify that the jaw has engaged the flange and that the top plate sits correctly across the bearing bars.
