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 and a base lock portion coupled to at least one of the plurality of base rungs, wherein the fly lock portion and the base lock portion selectively couple to one another to lock the base section and the fly section together to prevent inadvertent relative movement and retraction of the base section or the fly section relative to one another.

• a locking mechanism including a fly lock portion coupled to at least one of the plurality of fly rungs and a base lock portion coupled to at least one of the plurality of base rungs,
• wherein the base lock portion includes a socket disposed within the at least one of the plurality of base rungs,
• wherein the fly lock portion includes a flip lock coupled to the at least one of the plurality of fly rungs, the flip lock including a lock and a retractor, the retractor sized to engage at least a portion of the lock, and wherein the retractor includes a retractor spring to bias the retractor,
• wherein movement of the fly section relative to the base section causes the retractor to engage the lock and in turn engage the flip lock to the socket preventing inadvertent unlocking and retraction of the base section or the fly section relative to one another.
