Attach devices to grating surface

Model GM attach objectsModel GM-12
Available in Galvanized Carbon Steel.

Model SSGM-12
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.)

Model GM installedQuantities recommended
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 its parts.

Ordering information
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.
