HEADOFWALL DEFLECTION SYSTEMS
MaxTrak
®
 is a head-of-wall 
deflection track that is used for 
framing exterior curtain walls and 
nonload-bearing interior walls 
where vertical deflection occurs—
and serves as a connecting member 
that isolates the cold-formed steel 
framing system from the movement 
of the primary structure.
SLP-TRK
®
 slotted track provides a 
positive attachment for wall strength 
and allows for vertical movement. 
Movement caused by normal 
head-of-wall and floor extension or 
compression is absorbed by SLP-
TRK slotted track to prevent damage 
to the wall assembly. SLP-TRK 
slotted track systems comply with 
the toughest code requirements in 
North America.

It’s a real challenge these days meeting head-of-wall codes for fire stop and 
life safety issues while maintaining the ability to absorb vertical movement 
in low-, mid- and high-rise buildings. ClarkDietrich has the head-of-wall 
deflection products and systems you need for interior wall assemblies 
subjected to movement—including seismic disturbances.
