摘要： A telescopic edge protection post (1) arrangeable between a floor and a ceiling, wherein the telescopic edge protection post comprises an outer tube (2) having a floor end (3) and a top end (4), and an inner tube (5) having a bottom end and a ceiling end (7). Each tube has a polygonal cross-section. The inner tube extends into the outer tube and is movable with respect thereto between an extended position and a collapsed position. The post further has a locking mechanism (8) arranged to lock the inner tube with respect to the outer tube, and a tensioning device. The locking mechanism comprises a fixed element (9), which is attached to the outer tube at its top end, and a movable element (10), which is movable with respect to the fixed element between a locking position in which the movable element engages with the inner tube and the fixed element to prevent the inner tube from being retracted into the outer tube, and a non-locking position in which the inner tube is retractable into the outer tube. The movable element is arranged at a corner of the inner tube and is engaged with, at least in the locking position, first two adjacent sides of the inner tube at said corner. Thereby, when in the locking position, the movable element fixes the inner tube relative to the outer tube in all transverse directions of the telescopic edge protection post.
