The tilt angle on the 3-inch PV PoleTop is fully adjustable from 0 to 90 degrees by matching the tilt range of the 4-inch.

Albuquerque NM -- A new 3-inch top-of-pole PV rack today joins UniRac's proven family of PV PoleTops. Effective immediately, the company also begins certifying Design Wind Pressure ratings for all of its top-of-pole mounts for photovoltaic arrays.

New, Low Cost 3-Inch PV PoleTop. The new rack builds on the steady improvements made to UniRac's full line of PV Poletops over the past three years. Extensive testing and engineering analysis led to a 3-inch complement to UniRac's existing 2.5-inch and 4-inch PV PoleTops. The 3-inch features:

--Quick mounting T-bar. The new 3-inch incorporates the same all aluminum T-bar design as the comapny's 4-inch PoleTop. In many applications it can do the job of a 4-inch PV PoleTop, but at significantly lower cost.
--SolarMount HD rails. Quickly assemble arrays, with never a misaligned module mounting hole. All 3-inch and larger PV PoleTops use the heavy-duty rail, allowing long spans and high Design Wind Pressures.
--Lightweight, aluminum structural components. Most PV PoleTops use 100 percent aluminum structural components. All use stainless steel fasteners exclusively. Installers get both structural integrity and low shipping costs.

Certified Wind Pressure Ratings. UniRac now provides certificationýin writingýof the wind load rating for any specific PV PoleTop application. The certification covers the whole system: mounting pole, type and number of modules, tilt angle, and site exposure zone. This service is unique in the PV industry, and it's free.

The certification program continues UniRac's emphasis on code-compliant products and documentation to expedite building permits. Its SunFrame, SolarMount, and U-LA Large Array product lines already address code compliance.

UniRac devotes its entire business to the manufacture of PV module racks for every type of array and all makes and models of modules. It serves a worldwide market with installations from Chicago's Millennium Park to the Galapagos Islands. Its sales are particularly strong in the United States, Canada, Great Britain, and Australia.
