STEEL DOOR FRAMES
Both designs of CSA are secured through the inner most steel stud with 2 standard 1/2”
long pan head sheet metal screws per anchor. Figure 47 provides a typical completed
installation detail.
‘Z’ anchors, the second type of steel stud anchor, are used for non-standard jamb depth
double rabbet profiles in welded or knocked-down frames. Shown in Figure 48, they are
available in widths of 2”, 3”, 5” and 7” to suit jamb depths up to 9-3/4” and are
manufactured from 16 gage galvanneal steel.
These anchors are tack welded in two places to the inside of the profile at the factory or
distributor’s shop directly above or below the hinge reinforcings and directly opposite on
strike jambs. As with the CSA designs, ‘Z’ anchors are secured through the inner most
stud with 2 standard 1/2” long pan head sheet metal screws per anchor.
Figure 48 : ‘Z’ Anchor
Like masonry wall anchors, the number of anchors per jamb, when using CSA or ‘Z’
anchors is based on the height of the frame. Table 4 below details the requirements.
