Installation

Access to Interior

Step 1

 

TO OPEN DOORS:

 Access to the interior of S&C Pad-Mounted Gear is controlled 

by the S&C Penta-Latch® Mechanism, which must be opened with a pentahead socket 
wrench or tool except when hexhead actuators (Catalog Number Suffix “-B1” or “-B2”) 
are specified . The latching mechanism is coordinated with the provisions for padlocking 
such that the mechanism can be unlatched only after the padlock has been removed, and 
the padlock can be installed only after the door has been securely closed and completely 
latched .

Use a pentahead socket wrench or tool (a hexhead socket wrench or tool when Cata-

log Number Suffix “-B1”or “-B2” is specified) to unlatch the Penta-Latch Mechanism by 
rotating the actuator counterclockwise approximately 60º against spring resistance until 
a distinct “click” is heard and the actuator reaches its stop . Refer to Figure 2 . This single 
motion unlatches the mechanism and recharges the latching spring for the subsequent 
closing operation . Pull the door open and secure it with the door holder .

NOTICE

Do 

not

  force  doors  open . 

Forcing  a  door  open  can  damage  the  latching 

mechanism.

 

If optional key interlocks are furnished, correctly position the interlocks so the 

doors can be opened . 

For double-door models of pad-mounted gear, the left-hand door is secured closed 

by a rotating latch and is overlapped by the right-hand door which is equipped with the 
Penta-Latch Mechanism . The left-hand door can be opened after opening the right-hand 
door and disengaging the rotating latch . To disengage the latch, rotate it upward . See 
Figure 3 on page 7 . 

Unlatching  Penta-Latch  Mechanism 

with pentahead socket wrench—a dis-

tinct click indicates the mechanism is 

unlatched and recharged.

Opening door.

Closing door—firmly push door, mecha-

nism  latches  automatically  when  all 

latching points are engaged.
