Technical specifications:
bilaterally ascendable aluminium step ladder with four 80 mm self locking castors for the professional use in narrow spaces;
two additional compression-tension security devices ensure a safe link between the two ladder parts during use;
rails made of extruded aluminium profiles;
two weather-resistant safety straps with upright screwed and spark repelling metal latches prevent unintentional folding of the ladder;
screwed, 2-component footcaps: the hard component ensures a strong connection of the cap with the rail; the soft component provides a strong surface adherence and prevents the slipping of the ladder;
guiding and stop brackets stabilize the ladder parts during transport and storage.
