Ladders and ladder rungs

A rung for a ladder, the rung comprising:

• a first support surface portion;
• a second support surface portion;
• and
• a channel extending between the first support surface portion and the second support surface portion, wherein a first wall of the channel is planar, directly adjoins and extends below the first support surface portion, and is non-perpendicularly angled relative to the first support surface portion, wherein the first wall defines a plane, one side of the plane faces the entire first support surface portion, and an opposite side of the plane faces the entire second support surface portion;
• wherein the channel comprises a second wall, and the channel defines an upward-facing opening between the first wall and the second wall;
• and
• wherein the channel is configured to allow insertion of a substantial portion of a distal phalanx of a user's hand to allow grasping the rung.

A ladder comprising:

• a first assembly comprising:
• a first pair of spaced apart rails, at least one rail of the first pair of spaced apart rails including a front flange and a rear flange;
• a plurality of rungs extending between and coupled to the first pair of spaced apart rails, wherein at least one rung of the plurality of rungs includes a first support surface portion, a second support surface portion, and a channel extending between the first support surface portion and the second support surface portion, the channel having a floor portion positioned between a first rail of the first pair of spaced apart rails and a second rail of the first pair of spaced apart rails,
• wherein a depth of the channel is positioned rearward of the front flange and the rear flange;
• wherein the channel defines an opening spacing the first support surface portion and the second support surface portion apart from each other;
• and
• wherein the channel is configured to allow insertion of a substantial portion of a distal phalanx of a user's hand to allow grasping the at least one rung.

A ladder comprising:

• a first assembly comprising:
• a pair of spaced apart rails, wherein a rail depth is defined between a frontmost surface and a rearmost surface of at least one rail of the pair of spaced apart rails;
• and
• a plurality of rungs extending between and coupled to the pair of spaced apart rails, wherein at least one rung of the plurality of rungs includes:
• a first support surface portion having a first depth positioned in the rail depth,
• a second support surface portion entirely external to the rail depth, and
• a channel extending between and connecting the first support surface portion and the second support surface portion, at least partially positioned external to the rail depth, and defining an upward-facing opening between the first support surface portion and the second support surface portion, wherein the channel exhibits a height of at least 0.5 inch and a depth of at least 0.5 inch.

• wherein a depth of the channel is positioned rearward of the front flange and the rear flange;
• wherein the channel defines an opening spacing the first support surface portion and the second support surface portion apart from each other;
• and
• wherein the channel exhibits a depth of at least approximately 0.5 inch and a height of at least approximately 0.5 inch.
