The slat is used for smoothing concrete poured over large areas. The special vibrating head that attaches the slat causes the slat to be cycled, resulting in a better smoothed concrete surface. The operator can use the slat to smooth the surface at a distance of about 5 m from the place whereóry stands.

The lath (set) consists of five elementsów:

• smoothing plate with rounded sides, made of hardened aluminum (plate size: 120 x 20 cm; thickness approx. 6 mm)
• vibrating head mounted on a slat and folded
• 3 segments of lightweight aluminum plug (3x 180 cm; fi approx. 45 mm)
