A fall protection system includes a base assembly, a mast assembly, and a locking assembly adapted to lock the mast assembly with the base assembly. The locking assembly includes a first plate and a second plate. The locking assembly also includes a fixed member fixedly coupled to the second plate. The locking assembly further includes a locking pin including an elongate portion at least partially received within the fixed member and a first tab, the locking pin being movable relative to the fixed member between an engaged position and a disengaged position. In the engaged position, the first tab is at least partially received within a first groove such that the locking pin is engaged with the first plate. Further, in the disengaged position, the first tab is at least partially received within a second groove such that the locking pin is spaced apart from the first plate.
