SFA-16-1550 • Spine Frame Adapter

Polar Focus Spine Frame Adapter for tilt control. We offer a full line of audio rigging equipment and hardware for loudspeakers and line arrays.


Polar Focus Spine Frame Adapter™ is designed for either installation or portable use. Our Spine Frame Adapter SFA provides infinitely adjustable tilt control to a line array with the common front to back spine support frame configuration. Conforming to Polar Focus standards, this product has a 10:1 design factor. When combined with a Zbeam product, the SFA allows for precise control of pan and tilt under full load.

The SFA-16-1550 will accept standard anchor shackles from 5/16″ to 3/4″, allowing it to be attached to almost any common spine type line array frame. The tilt of the line array is adjustable under full load with a 9/16″ wrench, and can be locked down. For permanent installations, use blue thread lock under the locking nuts. Pan angle of the line array is controlled and adjusted by components not included on the SFA-16-1550. This product is compatible with any Polar Focus product with a part code beginning with ‘PY0’ or ‘PY1’, allowing simple system design. We offer a full line of structural attachment accessories for roofs, walls, poles, crank towers, lighting truss and motor adapters. Powder coated black, white, custom color, or galvanized.

This product is designed as part of the patented XY Grid® family of parts, and can only be used as supported by matching components within the family.
