WARNING! Risk of Damage or Injury
Improper mounting pin set-up may cause damage to the back pan and/or the
mounting plates. Ensure sufficient space is provided between the mounting plate
and the heads of the mounting pins (a minimum gap of 1/8" -1/4" (3mm-
6mm) is recommended).
The vertical (height) adjustment slots on each E2S/E2D back shell will vary in
length depending on the nominal back height- refer to Table 1.
