Vented stop bead apparatus, vented weep screed apparatus, and related systems and methods thereof

A vented weep screed apparatus comprising:

• a nailing fin having first and second sides;
• a first leg having a first leg portion extending from the first side of the nailing fin at a first location, wherein the first leg has a reverse leg portion extending back towards a plane of the nailing fin, wherein the reverse leg portion terminates at a position aligned with the plane of the nailing fin or past a plane of the second side of the nailing fin;
• and
• a second leg extending from the nailing fin at a second location, the second leg comprising a shelf connected to an upwards-facing surface by a riser, wherein the shelf is connected to a first edge of the riser and the upwards-facing surface is connected to a second portion of the riser, wherein the shelf is positioned vertically above the upwards-facing surface by the riser, and wherein the upwards-facing surface has a continuous downwards slope;
• and
• at least one venting structure positioned through the shelf of the second leg.

A system for venting a wall formed of at least one of stucco and plaster, the system comprising:

• a vented weep screed positioned proximate to a bottom edge of the wall and connected to a wall backer, the vented weep screed having at least one venting structure positioned through a leg thereof;
• a vented stop bead connected to the wall backer and positioned proximate to a top edge of the wall, the vented stop bead having at least one stop bead venting structure positioned therethrough;
• and
• a rain screen positioned between the vented stop bead and the wall backer, wherein the rain screen extends along the wall backer between the vented stop bead and the vented weep screed, wherein a venting path is created from the at least one stop bead venting structure of the vented stop bead, through the rain screen, and through the at least one venting structure of the vented weep screed.
