A single case size is used for most models of Magnehelic
®
gages. They can be
ush or surface mounted with standard hardware supplied. Complete mounting and
connection ttings plus instructions are furnished with each instrument. A 4-9/16˝ hole
is required for ush panel mounting.
Flush mounting is easily accomplished with the new A-300 Flush Mounting bracket.
This bracket provides a solution to quickly and conveniently ush mount the
Magnehelic
®
gage. The A-300 is ideal for mounting the Magnehelic
®
gage on control
panel doors.
The A-368 is a simple bracket for quickly surface mounting the Magnehelic
®
gage.
After securing the Magnehelic
®
gage to the A-368 bracket, mount the bracket on any
at surface.
The A-369 allows the Magnehelic
®
gage to be easily carried to locations where
pressure readings need to be taken. The A-369 can stand on its own or hang on a
nail or hook.
