Abstract (en)
Embodiments include a telescoping ladder with a plurality of retaining mechanism. The telescoping ladder has a plurality of columns in a nested telescopic arrangement. The retaining mechanism positioned on an outer surface of a column prevents extending columns other than an immediately inner column from their nested arrangement until the immediately inner column is fully extended from its nested arrangement with an outer column.
