CBA-4 • Custom Beam Attachment • Type 4

Polar Focus Custom Beam Attachment for rolled wood beams. We offer a full line of audio rigging equipment for professional loudspeakers and line arrays.


Polar Focus Custom Beam Attachment Type 4 – made to order for professional audio loudspeaker rigging. Type 4 CBA is for attachment to a rolled wood beam and provides a rigging point that can mount a Zbeam arm or a yoke (u-bracket) or other components. Parts which attach to the bottom of the CBA Type 4 are sold separately. Polar Focus CBA’s can be powder coated in black, white, or your choice of custom color.

Sometimes there is just no way to safely attach to a roof structure with any stock components for a speaker rigging project. This is especially true when attaching to large laminated or solid wood beams in house of worship installations.

Please note, wood laminated beams are frequently sized slightly off (larger) than the architectural drawings may indicate. Also, a beam at one end of the building may be slightly different than a beam at the other end. We prefer to build to actual measurements of the specific beam under consideration.

Sloped steel beams also may require custom beam attachment since standard beam clamps are not rated for use on sloped beams, and some jurisdictions will not allow for a friction connection on a sloped beam.
