Single Sided Angle Method:

 For single side installations the retaining angles must be attached to the wall/floor  

(see 

Figures 8-11

). For metal stud partitions only, the single side mounting angle may be directly attached to the 

metal stud prior to the installation of the drywall.
  •  Retaining angles must be attached to the partition using one of the methods shown below:
    -  #10 screws of a length such that the screw engages the steel stud/track by ½ in. (13 mm) (steel framing).
    -  #10 screws of a length such that the screw engages the wood stud by 13/4 in. (44 mm) (wood framing).
    -  Steel anchors or self tapping concrete screws penetrating masonry or block 11/4 in. (31 mm).
  •  A minimum of two connections per side are required. Additional connections made at a maximum of 12 in. (305 

mm) O.C. for openings of 48 in. W x 36 in. H (1219 mm x 914 mm) and less. Dampers greater than 48 in. wide 
(1219 mm) or 36 in. high (914 mm) require the connections to be no more than 6 in. (152 mm) O.C.
