20ft blade for MBW ScreeDemon power screed
(manufacturer # 17820)
(click to enlarge)
The magnesium screed bar is designed to work within the natural frequency of the screed/bar combination. The back-to-back double triangular design is very rigid and offers comparatively uniform vibration along the full length of the bar. The result is a more uniformly vibrated slab complete with uniform fine depth at the surface. This design also allows for offsetting of screed for working under protrusions. These blades simply clamp to the specially designed bar. No holes to weaken the screed bar. No threads to complicate. Attach or remove in seconds for cleaning or transport.
The 18, 20, and 24 ft blade require two ScreeDemon power units.
