One Systems, Inc. offers a variety of U-Brackets for use with its Platinum Hybrid loudspeaker
systems. U-Brackets provide an easy way to achieve a vertical or horizontal wall mounting, or
a ceiling parallel mount for loudspeaker systems."
Special Note: All U-Brackets for standard One Systems products are made with 316grade stainless steel and are listed below.
Caution should be exercised when attaching One Systems Marine grade products and
Marine grade rigging to other metallic, non 316-grade stainless steel surfaces (dissimilar
metals). The potential for galvanic corrosion is high in marine environments where the
One Systems enclosures and rigging are specified or required. Compatible metals and
appropriate anode-to-cathode area ratios must be maintained. A structural engineer
with galvanic corrosion experience should be consulted prior to installation of marine
grade products, or ANY One Systems products in marine environments.
The following One Systems models may be mounted using a U-Bracket:"
##✓ 104.HTH* (U-Bracket included with the speaker)"
##✓ 106.HTH* (U-Bracket included with the speaker)"
##✓ 108.HSB"
##✓ 108.HTC"
##✓ 108/HTH"
##✓ 208.HTC"
##✓ 112.HTH"
##✓ 118.HSB"
##✓ 212.HC"
##✓ 312.HC"
##✓ CFA2.HTH"
Important Note: All products used in direct weather installations can be subjected to
high wind speeds. For wind speed exposure over 74 miles per hour (119.1 kilometers per
hour, 64.3 knots), the loudspeaker enclosure, bracket and safety chain must be
inspected for signs of damage or fatigue!
