Attach 2″ Square Mesh Fiberglass Grating to structural shapes.
G-Clip model ZSSGG is a 316-stainless steel grating fastener used to fasten 2″ square mesh fiberglass grating to structural shapes where the structural flange is in a horizontal plane. Specially shaped top assembly is designed to fit 2″ square mesh.
G-Clip model ZSSGG – fastener consists of three parts, which are assembled at the factory into a complete installation unit, packed 50 units to a standard box.
The 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, toothed shape segments facing upward, which contact the underside of the structural member. The second part is the specially-shaped, stamped top, which fits into the grating upper surface and presses downward around the tops of the square.
The body and top are joined by a 1/4″ -20 threaded bolt, in proper length for the application.
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.
G-Clips can be installed using a handheld 7/16″ nut driver.
Hold the G-Clip square 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.
Common handheld 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.
When severe vibrations are anticipated or structural movements may occur, a higher torque value can be used. Stainless steel G-Clips can withstand installation torques of 100 inch/pounds without damage to the fastener, which is removable and reusable.
HOW TO ORDER
Determine the total height of grating and thickness of the flange area. Describe grating configuration to specify proper top assembly to suit grating being installed.
We recommend using a grating fastened point for every four (4) square feet of grating, on average, pedestrian conditions. Where vibration is present more fasteners should be used. Grating manufacturers’ recommendations should be consulted for further information.
