Climbing product having an extendable section lock assembly

A ladder comprising:

• a base section including a first base rail and a second base rail, the second base rail in a space relation to the first base rail;
• a fly section including a first fly rail and a second fly rail, the second fly rail in a spaced relation to the first fly rail;
• a plurality of base rungs attached to and extending between the first base rail and the second base rail;
• a plurality of fly rungs attached to and extending between the first fly rail and the second fly rail;
• and
• a locking mechanism including a fly lock portion coupled to at least one of the plurality of fly rungs, a base lock portion coupled to at least one of the plurality of base rungs, wherein the fly lock portion includes a flip lock and a plunger, and wherein the locking mechanism, via the flip lock and the plunger engaging one another, prevents inadvertent unlocking and movement of the base section or the fly section relative to one another, and
