Remove both lower sash end caps.
1. Raise the lower sash so you can comfortably reach the
underside of the sash handle rail. If the sash travel has
been limited, the limit stops may have to be removed.
2. The carrier body is located in the jamb pocket at the
bottom end of the sash side rails. A hook in the bottom of
the carrier body is held in place by a flex spring. Insert a
flat blade screwdriver between the upturned edge of latch
and bottom of carrier. Pry screwdriver towards center
using corner of sash as a pivot point until latch snaps free
of carrier guide.
3. Latch should now be hanging against the back of the
jamb channel. Lower the sash slowly until the carrier
body hook is below the jamb hold down blocks. Raise the
sash again until the hooks engage the jamb hold down
blocks. The carrier body will be held in place when the
sash is removed
