bolts do not meet installation requirements, prepare M6 stainless steel expansion bolts
by yourself.

● To prevent dust inhalation or contact with eyes, wear safety goggles and a dust
mask when drilling holes.
● Use a vacuum cleaner to clean up dust in and around the holes, and measure
the spacing. If the holes are inaccurately positioned, drill the holes again.

nut, spring washer, and at washer. Otherwise, the mounting bracket will not
be securely installed on the concrete wall.
