Model RGGAttach Various Bar Gratings to metal or other structural shapes.

Model RGG
Galvanized Carbon Steel

Model RSSGG
316-Stainless Steel


G-Clip model RGG is available in galvanized or 316-stainless steel. It is a grating fastener used to fasten bar grating to metal or other structural shapes,where the structural flange is in a horizontal plane. The model "R" top is a circular-shaped top, 2-1/8" diameter, 16 -gauge stamped steel, in the shape of a shallow volcano. A dimpled center allows hex-head cap screw to fit into the recess. Fits many odd-shaped grating bar setups.

G-Clip model RGG- fastener consists of three parts, which are assembled at the factory into a complete installation unit, packed 50 units to a standard box.

Principal part is the body assembly, which has a female thread form in its upper portion. Body lower portion is die-stamped, with die-cut jaws facing upward, which contact the underside of the structural member. Second part is the rounded, stamped top, which fits onto the grating upper surface. The body and top are joined by a 1/4" -20 threaded bolt, in proper length for the application.

Installation Preparation
As with any grating fastener, care should be taken during the grating layout, cutting and placement phase, to reduce the quantity of grating bars that are located over the structural member flange edge. This reduces the quantity of grating cross bars that interfere with fastener placement, which otherwise requires cutting of cross bars.

Tools Required
G-Clips can be installed using a handheld 7/16" nut driver.

Installation Guide
Hold the G-Clip top in hand, allowing the body portion to hang downward. Fit the body between two bearing bars and lower the unit until the body is below the grating bottom. Slide unit laterally toward, and allow it to fit under, the structural member flange. Pull upward on the top of the G-Clip, holding upward force. With the formed lower-body secure under the flange area, tighten the bolt with a 7/16" wrench, to complete the installation of the G-Clip unit.

Torque Measurements
Common hand held nut drivers have a handle diameter of 1" to 1-1/4", which will allow installation torque (resistance to further tightening) of approximately 60 inch/pounds to be easily achieved. This is sufficient for many installation requirements. Electrical or pneumatic tools are often used on large grating surface areas. Do not exceed torque values of 100 inch/pounds if fastener reuse is desired.

How to Order
Determine total height of grating and thickness of flange area.

Quantities recommended
We recommend using a grating fastened point for every four (4) square feet of grating, in average, pedestrian conditions. Where vibration is present more fasteners should be used. Grating manufacturers' recommendations should be consulted for further information.
