I am designing a light gage steel head support for an 18 ft. tall curtainwall system. The curtainwall vertical mullions are about 5 ft. O.C.. My framing is rigidly attached to the structure so CW installer will need to use deflection clips on his system. Does anyone if the clips can only be installed at the vertical mullions or can they be installed at a tighter spacing - such as 16" O.C. The reason I ask is that a deflection clip will add a localized moment and prying to the track of my header due to the eccentricity. (I assume anyhow - unless that somehow gets reacted into the mullion) I would like to minimize this stress.
Thanks
