These are non-bearing partition walls with a height of about 16’. They definitely need slip track at the top of the metal studs.

If the walls are bearing walls, they will NOT have slip tracks.

• The purpose of slip tracks for non-bearing walls is the metal stud can expand and move along the slots in the slip tracks when temperature is high. This will avoid compression to the metal studs which can cause buckling for the non-bearing studs.

• Hi Gang, is this detail not a slip track? Also what is the difference between a slip track and slip channel? I couldn't find info about slip channel on google. Thank you so much.

• No, this detail is not a slip track. A slip track and a slip channel are two different names for the same thing.

• These are what slip tracks look like in detail and photo:

• I'm still confused. Isn't that section representing a slip track? If not, what is it?

• No, the section in the original question is NOT a slip track, it is just a regular stud wall with fixed top track.

• Then is the detail difference between a slip track and a top track matter of line weight?

• For slip track, the top track has slots on both sides of the track, allowing fastener vertical movement of up to 1 ½”. Graphically, there is also a gap (up to 1 ½”) from the top of the vertical metal stud to the top track.

Just to be clear so I'm not misunderstanding, the difference between A and B is the stud not showing in A, so can be assumed that it is a regular stud wall?

• The biggest difference graphically is the gap:

• In your samples above, both a and b have the stud shown, but b has the gap. a has the stud all the way to the top.
