WYCO 20' Screed Bar For Double Power Unit - WS621450
The Screed King is easy to use and saves time, service and manpower while providing the best finished concrete quality. The unique magnesium power bar and power transfer system produces a high frequency vibration that eliminates the honeycomb effect and speeds finishing time. Screed King allows one person to do the work of two in less time as compared to traditional 2x4 screeding. Screed King can pay for itself in the first few pours. The Screed King is available in a variety of configurations, with multiple board lengths that can be removed without tools. Screed King also features the option to run boards longer than 16ft. with dual power heads.

What our Experts Think
-
Engineered for long pours: The WYCO 20′ Screed Bar For Double Power Unit – WS621450 extends screeding reach to 20 feet with dual power heads, letting one operator handle wide slabs efficiently while maintaining consistent concrete finish quality.
-
Lightweight magnesium construction: Made from light magnesium, this screed bar is significantly lighter than aluminum alternatives, making it easier to maneuver on large pours while resisting corrosion or reaction with concrete.
-
Float‑friendly 6″ base: The 6″ base helps the bar float smoothly across varying concrete slump conditions, improving surface consistency and reducing high or low spots.
-
Curl edge for cleaner results: Curl edges roll excess concrete back toward the operator, aiding more uniform beveling and smoother screeding motion.
-
Durable, enclosed design: An enclosed profile prevents warping or torque damage, keeping the board straight and reliable through repeated heavy use.
-
Tool‑less board removal & cleaning: No tools are needed to attach or detach the screed board, and the simplified design — with no brackets or torsion rods — makes cleanup fast after pours.

A: The screed board is 20 feet long and weighs about 69 lbs, offering a long reach while remaining manageable for transport and assembly.
Maintenance Tips
-
Inspect Before Use: Check the screed bar for bends, cracks, or excessive wear to ensure straight, level concrete finishing.
-
Clean After Each Use: Remove concrete residue and debris immediately to prevent buildup and corrosion.
-
Check Fasteners & Connections: Ensure all bolts, pins, and attachment points to the power units are secure before operation.
-
Lubricate Pivot Points: Lightly oil any adjustable or pivoting parts to maintain smooth movement.
