4. The PT-76a, PT-38a, PT-30 and PT-10 pan and tilt brackets should be
installed only by someone experienced in the overhead suspension of 
items. They should be familiar with applicable local/national codes 
governing the installation of these types of products and those governing 
the attachment of these types of products to specific pole structures. 
 
5. 
The PT-76a and PT-38a are available in both 304 grade and 316 (Marine) 
grade stainless steel. If the Marine grade version (316 stainless steel) is 
being used then all associated rigging must also be 316 grade stainless 
steel. If the PT-30 Marine grade product is being used please note that 316 
grade Band-It straps are required. 
NOTE:
Caution should be exercised when connecting 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 Marine grade 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. 
 
CAUTION: All structures outdoors are subjected to wind forces. These forces must be 
considered when suspending any product outdoors. It is necessary to know the 
“Effective Projected Area” (EPA) of the loudspeaker prior to installation of the 
loudspeaker and the PT-76a, PT-38a, PT-30 or PT-10. See Appendix 1 of this 
installation manual for effective projected areas for each enclosure rated for use with 
the PT-76a, PT-38a, PT-30 and PT-10. 
 
IMPORTANT NOTE: All products 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, banding, and link assembly or safety must be 
inspected for signs of damage or fatigue! 
INSTALLATION
NOTE: See separate instructions below for the PT-10 and PT-30
The PT-76a and PT-38a consist of three parts: the wall bracket, the loudspeaker 
bracket, and the Link. The PT-76a wall bracket and loudspeaker bracket are shown in 
Figure 1. Figure 1a shows the wall bracket portion of the PT-76a. The PT-76a bracket 
allows the loudspeaker to be oriented from a 0 degree down tilt to a maximum down tilt 
of 35 degrees in 5 degrees increments. The PT-38a allows a down tilt of 40 degrees in 
8 degree increments.
