Description

Drive smoother, more consistent concrete pours with a wet screed engineered to eliminate the failures of traditional bolt‑on systems.

Built to reduce maintenance and speed up every slab pour.

501H-Vibratory ScreeDemon

Handle larger pours with a gas‑powered wet screed built for steady vibration and long pulls. The 501H uses a Honda engine to drive consistent energy through the screed bar, helping crews achieve smoother strike‑off results on medium to large slabs.

Its handle configuration supports stable control during extended passes, and the lightweight frame helps reduce operator fatigue. Magnesium and aluminum bars are available in multiple lengths to match different pour widths and jobsite conditions.

This model is suited for outdoor work and open environments where gas power provides the runtime and output needed for continuous production.
