HEADOFWALL DEFLECTION SYSTEMS
ClarkDietrich Fast Top™ clips are 
used in head-of-wall deflection 
conditions for in-fill curtain wall 
assemblies to provide for vertical 
movement. These clips are used 
in place of, or in combination 
with, deflection track. They also 
make a positive attachment and 
eliminate the need to install bridging 
continuously throughout the upper-
most punchouts. Attach to the 
underside of structural members, 
concrete decks or floor assemblies. 
Studs must be cut less than full 
height to enable vertical movement 
up to 2-1/2" (1-1/4" up and down).

Fast Top™  C L I P 
This traditional assembly allows for 
the deflection of floor beams or 
floor decks above interior partitions. 
The single, long leg track assembly 
requires 1-1/2" cold-rolled channel 
(CHN2) and 1-1/2" x 1-1/2" 16 gauge 
EasyClip™ Clip Angles (U-Series™), 
installed continuously throughout 
the upper-most punchouts (must 
be a maximum of 12" from the top 
track), to align the studs vertically 
within the plane of the wall.
ClarkDietrich DoubleTrack™ 
system is a two-piece top track 
assembly that allows for the 
deflection of floor beams or floor 
decks along interior partitions. A 
custom-made long leg outer track 
is installed to the underside of 
the floor deck. A wall assembly is 
constructed on the floor then slid 
into place. The wall assembly is 
designed to allow a “gap” at the top 
for deflection.
