Outer 1/2” Holes
Center 1/2” Hole
1/4” Holes
LOAD RATINGS
Multiple holes are provided in the top surface of the MUB-1D U-bracket that accommodate a variety of hardware that
can be used to suspend the device or secure it to a surface.
Please note that each of the MUB-1D U-bracket’s mounting holes or sets of holes have individual load ratings. These
are shown below.
WARNING: When ying an array from the MUB-1D U-bracket, it must always be supported by pick-up
holes whose ratings meet or exceed the weight of the array.
Maximum Load Ratings:
Two Outer 1/2” Holes:
7:1 safety factor: Up to 10 M1Ds (320 lbs, 145 kg)
5:1 safety factor: Up to 14 M1Ds (448 lbs, 203 kg)
NOTE: Load evenly distributed on
the two points.
One Center 1/2” Hole:
7:1 safety factor: Not rated
5:1 safety factor: 1 M1D (31 lbs, 14 kg)
Four 1/4” Holes:
7:1 safety factor: Up to 3 M1Ds (96 lbs, 44 kg)
5:1 safety factor: Up to 4 M1Ds (130 lbs, 59 kg)
NOTE: Load evenly distributed on
all four points.
WARNING: Always use mounting and rigging hardware that has been rated to meet or exceed the
weight of the loudspeakers being hung.
