The ClarkDietrich Heavy-Duty Stud 
(HDS
®
) Framing System provides 
outstanding bending strength in two 
directions and superior axial strength. 
Plus, it reduces material, labor costs 
and installation time by up to 50%. 
The superior strength and carrying 
capacity of the HDS means higher 
performance with fewer members, 
like eliminating box beam headers, 
nesting track and stud for posts and 
jambs. It also means improved finish 
quality by eliminating excessive 
material and screw head buildup 
around doors and windows. 
• Use for curtain wall headers, jambs 
and sills; drywall headers and jambs; 
load-bearing jambs, and more.
• Openings up to 15' wide
• Eliminates multi-member  
built-up truss chords and webs
• Improves drywall finishing 
around doors and windows
Ultimate load capacity for headers and jambs.

eliminates surface head fastener 
buildup that can create finishing 
challenges.
