The Sport-Thieme volleyball posts 80x80 mm DVV 2 are available in two versions. These particularly stable posts are ideal for competitions, as only posts with approval marks 1 or 2 are permitted for matches and tournaments in the upper leagues, state leagues, and association leagues. The posts are manufactured according to DIN EN 1271. They come in two designs: a pulley system or a spindle tensioning device. All control elements are housed within the integrated casing. The net height can be continuously adjusted from 1.55 to 2.50 m. For DVV 2 posts, the net tension must be released for this adjustment. In contrast, for DVV 1 posts, the net can be adjusted continuously from 1.55 to 2.50 m in a fully tensioned state without the need for readjustment or retensioning.
