UNIBOOM®P Series booms are kept vertical by means of floats placed symmetrically on both sides of the boom fabric (very heavy duty PVC- coated polyester), giving rise to a strong, hard- wearing construction which is easy to maintain and repair on site. Markleen UNIBOOM®P Series booms are long lasting booms with rigid foam-filled polyethylene floats. Uniboom P Series booms are made to give a particularly long service life in installations where they are used frequently or permanently.
