         8 . The metal lath accessory of  claim 1 , wherein the first flange comprises a first plurality of openings. 
     
     
         9 . The metal lath accessory of  claim 8 , wherein the second flange comprises a second plurality of openings. 
     
     
         10 . The metal lath accessory of  claim 9 , wherein each of the first plurality of openings in the first flange is aligned with a corresponding one of the second plurality of openings in the second flange. 
     
     
         11 . The metal lath accessory of  claim 1 , wherein the first flange further comprises an angled portion located at a free end of the first flange. 
     
     
         12 . The metal lath accessory of  claim 1 , wherein the first barb comprises a substantially triangular cross-section. 
     
     
         13 . The metal lath accessory of  claim 1 , wherein the side wall, the first flange, the second flange and the first barb are of unitary construction. 
     
     
         14 . A metal lath accessory comprising:
 a. a side wall;   b. a first flange comprising a first plurality of openings, wherein the first flange extends from the sidewall in a first direction;   c. a second flange, wherein the second flange extends from the sidewall in the first direction such that the first flange and the second flange are spaced apart from each other;   d. a first plurality of barbs, wherein the first plurality of barbs project from the first flange toward the second flange, wherein at least one of the first plurality of openings is positioned between a pair of adjacent barbs of the first plurality of barbs.   
     
     
         15 . The metal lath accessory of  claim 14 , wherein the second flange comprises a second plurality of openings. 
     
     
         16 . The metal lath accessory of  claim 15  further comprising a second plurality of barbs, wherein the second plurality of barbs project from the second flange toward the first flange, wherein at least one of the second plurality of openings is positioned between a pair of adjacent barbs of the second plurality of barbs. 
     
     
         17 . The metal lath accessory of  claim 14 , wherein at least one of the first plurality of openings comprises a substantially triangular opening. 
     
     
         18 . The metal lath accessory of  claim 14 , wherein at least one of the first plurality of openings comprises a substantially trapezoidal opening. 
     
     
         19 . An assembly comprising
 a. a metal lath accessory, wherein the metal lath accessory comprises
 i. a side wall, 
 ii. a first flange, wherein the first flange is connected to the side wall, 
 iii. a second flange, wherein the second flange is connected to the side wall, 
 iv. a channel, wherein the channel is at least partially defined by the side wall, the first flange and the second flange, and 
 v. a first barb, wherein the first barb projects from the first flange into the channel; 
   b. a piece of metal lath, wherein the piece of metal lath comprises a plurality of openings, wherein the piece of metal lath is inserted into the channel such that the first barb engages the piece of metal lath via one of the plurality of openings in the piece of metal lath.
