Ladders, ladder accessories, components thereof, and lock assemblies for use therewith

A rail assembly comprising:

• a first rail including a first opening extending therethrough;
• a second rail opposite the first rail, the second rail including a second opening extending therethrough;
• and
• a lock assembly disposed between the first rail and the second rail to selectively engage the first opening and the second opening, the lock assembly including:
• a first rod having a proximal end portion adjacent to the first rail and a distal end portion opposite the proximal end portion, the distal end portion of the first rod coupled to a first lever;
• and
• a second rod having a proximal end portion adjacent to the second rail and a distal end portion opposite the proximal end portion, the distal end portion of the second rod coupled to a second lever, the second lever creating a pinch grasp portion with the first lever;
• the lock assembly having a locked position in which one or more of the proximal end portion of the first rod engages the first opening and the proximal end portion of the second rod engages the second opening, and an unlocked position in which one or more of the proximal end portion of the first rod disengages the first opening and the proximal end portion of the second rod disengages the second opening.

A ladder comprising:

• a first section including a first left rail and a first right rail opposite the first left rail;
• and
• a second section including a second left rail and a second right rail opposite the second left rail, the second section having a lock assembly disposed between the second left rail and the second right rail, the lock assembly including:
• a right rod having a proximal end portion adjacent to the second right rail and a distal end portion opposite the proximal end portion, the distal end portion of the right rod coupled to a right lever;
• and
• a left rod having a proximal end portion adjacent to the second left rail and a distal end portion opposite the proximal end portion, the distal end portion of the left rod coupled to a left lever, the right lever creating a pinch grasp portion with the left lever;
• the lock assembly having a locked position in which one or more of the proximal end portion of the right rod engages the first right rail and the second right rail and the proximal end portion of the left rod engages first left rail and the second left rail, and an unlocked position in which one or more of the proximal end portion of the right rod disengages the first right rail and the second right rail and the proximal end portion of the left rod disengages the first left rail and the second left rail.
