On Stage Subwoofer Attachment Shaft with M20 Thread

More and more pole mount subwoofers are hitting the market with M20 threaded pole mounts instead of the older 1-3/8" socket design. The advantage is obvious: no tilt and wobble!

The OSSS7746 is designed for this new breed of subwoofers. Its all steel shafts telescope from 30"- 54", held tight with a friction locking knob backed up by a captive steel security pin.
The lower shaft features 41 mm diameter steel tubing terminated with a zinc plated threaded lug.
The upper shaft is sized to fit satellite speakers with standard 1-3/8" pole mounts.

Shaft Length Adjustable: 30" - 54"
Weight Capacity: 80lbs
