6. Question
Bumpers are used to restrain the base from moving horizontally when there is __________ that the equipment will tip over.
CorrectIncorrectHint
Bumpers are used to restrain the base from moving horizontally when there is no chance that the equipment will tip over. Bumpers are only bolted to the building structure. Use post-installed anchors to bolt to concrete, as shown in Figure 76 and 77.

13. Question
What versatile attachment can be used for in-line piping assemblies secured by wall mounting?
CorrectIncorrectHint
A versatile attachment is an angle welded to a base plate, as shown in Figure 126. This can be used for inline piping specialties or for equipment. Two supports on each side of equipment may be required. Rigid connection with rods and cables supported from the building structure above is optional.
