Abstract
A telescopic edge protection post arrangeable between a floor and a ceiling, comprising outer and inner tubes, each comprising a bottom end and a top end, the inner tube extending into the outer tube and being movable with respect thereto between an extended position and a collapsed position. The post further comprises a locking mechanism to lock the inner tube with respect to the outer tube in the extended position, and a tensioning unit arranged at the top end of the inner tube. The tensioning unit comprises a tensioning element having a primary and secondary tensioning portions, wherein tensioning of the secondary tensioning portion requires a lower force than the primary tensioning portion, allowing tensioning of the secondary tensioning portion by extending the telescopic edge protection post by hand into engagement with the floor and the ceiling. Further, the primary and secondary tensioning portions each comprise a compression spring.
