NB-048 Professional Crank-Up Speaker Pole with M20 Threaded Mount
Product Overview
The NB-048 is a professional adjustable speaker pole designed for mounting full-range PA speakers above subwoofers, speaker bases, or other compatible support systems.
Its manual crank mechanism provides smooth height adjustment from 830 to 1,470 mm, making it easier to position the loudspeaker at the required height. Locking knobs help secure the pole after adjustment for dependable use during performances and installations.
The standard 35 mm upper tube is compatible with most pole-mount PA speakers, while the reinforced 42 mm main tube provides stable support. An M20 threaded connection at the bottom allows the pole to be securely attached to a compatible subwoofer or speaker base.
