bar grating to flanges of angle shapes or channel shapes, where
the flange of the shape is in a vertical plane.
G-Clips model GA- fastener consists of three
parts, which are assembled at the factory into a complete installation
unit, packed 50 pieces into a standard box. Principal part is
the lower body assembly, a J-shaped assembly with a female thread,
which hooks under the underside of (vertical) structural shape.
Second part is the stamped top, which fits over the grating upper
surface. 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 cross 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 to hang downward. Fit the body between two bearing
bars and lower the unit until the body is below the grating bottom.
Downward-hanging shape must be hooked under the vertical member
and drawn upward, while the fastener bolt is tightened. Pull upward
on the top of the G-Clip, holding upward force, with the formed
lower-body secure under the structural member. Tighten bolt to
complete the installation of the G-Clip unit.
Common handheld nut drivers have
a handle diameter or 1" to 1-1/4", which will allow
installation torque of approximately 60 inch/pounds to be easily
achieved. This is sufficient for many installation requirements.
Electrical or pneumatic-driven tools are often used on large grating
surface areas. Do not exceed torque values of 150 inch/pounds,
if fastener reuse is desired.
How to Order
Determine total height of grating, and thickness of flange area.
