2. Mount the chassis (inner) member onto the chassis.
You may opt for M4 or M5 pan head screws. The screw
head of either M4 or M5 can not exceed 2.0 mm.
Alternatively, you may mount the slide member onto the
chassis through standoffs. Likewise, the head of stand-
off can not exceed 2.0 mm. Each side of chassis uses 3
screws or standoffs for each slide attachment.
3. Attach the cabinet (outer) member to the rail.
Insert the stag into the upper and lower square holes
on EIA rail from the back of the rail. Push the safety lock
forward to secure the bracket. It is important to check if
the safety lock is in an unlocked position before mount-
ing the brackets.
4. Mount the chassis into the cabinet.
Insert the chassis (inner) member into the cabinet as
shown on the drawing. It is important to check if the ball
retainer is in a fully open position before installing the
chassis. It might cause damage to the chassis if ball
retainer is not in the fully open position while mounting
the chassis. While you are pushing chassis back to the
cabinet, you need to release the slide from the locking
position by pressing the trigger down.
