devices to grating surface
Available in Galvanized Carbon Steel.
Available in 316-Stainless Steel.
The model GM- describes
an assembly of fastener parts that can be used as a stable base
on which to mount other devices to a grating surface. Assembly
consists of a 1/2 " stud about 3 " long, which contains a patented
bottom part that holds captive a 1/2" nut. Top part is a generous-sized
plate with a 1/2" diameter threaded hole, which sits above the
grating, and is tightened down to complete the fastener installation.
This provides a remaining stud length above the grating onto which
can be fastened devices as desired.
How to install
Model GM- can be installed entirely from
above the grating surface. Hold the device from its upper studs
end, and allow the bottom stamped piece to fit down into, and
below, the grating lower surface. Rotate the fastener 90 degrees,
allowing lower unit wings to trap under the grating bars, preventing
further turning of the bottom. Then, pull upward on the stud,
and hold. Turn the upper plate, clockwise, until tight, using
either a 2" opening wrench or a GM- installation tool (See "Tools
and Accessories" for more information.)
Most larger devices, such as panel enclosures,
require four (4) mounting devices. Each model GM-1/2" can withstand
1,000 pounds of upward pulling force without distorting any of
Available in boxes of 20 assemblies. These
devices are usually in stock and can be shipped same day if ordered
before 2:00 p.m. CST.
