The brackets are constructed of heavy gauge steel, with standard or red corrosion resistant baked-on powder paint. Tough resilient pads are firmly attached to the clamp arm and the bracket base to provide two points of restraint for outstanding extinguisher security. The toggle action clamp arm is adjustable so that the best fit may be maintained throughout the bracket’s long life. As with all ANSUL brackets, the extinguisher may be removed or replaced in the bracket quickly and easily. Holes are provided for mounting the bracket by the back plate or by the base

The heavy duty/vehicle bracket has successfully withstood vibration tests at forces which equal those indicated by vehicle manufacturers as the maximum they anticipate. These forces are 5 g’s parallel to the length of the bracket back and 1 g in the planes perpendicular to that, as shown in the following figure. The bracket may be mounted in many different orientations on a flat supporting surface that is vertical, horizontal, or slanting.
