3. Place the drawer enclosure in the vehicle in the desired mounting location and mark where the (6) side mounting
holes should be located (3 per side)
WARNING! - Make sure that there is nothing under the vehicle that will be damaged by the drill bit when drilling.
4. Remove the Enclosure from the vehicle. Drill the (6)
3/8” side mounting holes into the truck bed. It is recommended
to use silicone sealant on any drilled holes to prevent rusting.
5. With the enclosure placed in the desired mounting location insert the
(6) #35.14 3/8” bolts with (6) #35.13 3/8”
washers through the mounting brackets on the Enclosure, then through the holes drilled in the truck bed. Install (6)
#35.13 3/8” washers and (6) #35.12 3/8” nylock nuts from under the truck bed. (See Figure 2)
OPTIONAL SECURITY STEP
WARNING! - Make sure that there is nothing under the vehicle that will be damaged by the drill bit when drilling.
For additional security, mark the spot in the vehicle floor under the additional hole in the drawer enclosure mounting
flange and drill a 3/8” hole. Fasten using the included bolt #35.14, washers #35.13 and nut #35.12. It is recommended to
use silicone sealant on any drilled holes to prevent rusting. (See Figure 2)
6. Insert the drawers and test the operation. Make sure there is clearance between the drawer handles and the rear
tailgate. Test to make sure that access to any important compartments in the floor or side panels are maintained.

ATTENTION:
FREQUENT LUBRICATION IS NECESSARY ON THE LOCKING SYSTEM
The pushbutton lock contains an “O” ring seal to protect the interior from dust and water. If this mechanism is not
lubricated regularly it will become difficult to operate and it may not return to its home position preventing the key from
operating the lock. If this happens simply pull up on the pushbutton to manually bring it back to its home position.
Lubricate the pushbutton with a light lubricant such as silicone spray. The pushbutton may have to be periodically
disassembled and cleaned.
Required Periodic maintenance: Failure to perform periodic maintenance can result in the loss of access inside
the security enclosure and failure of components.

Lubrication is required for all moving parts. The schedule will vary depending on the level of usage and
environmental conditions. Once a month is a good starting point. Be sure to lubricate all friction points
completely. Use high temperature lithium grease. Key lubrication points are shown on the illustration below
for the latch system with the optional pushbutton combination lock. Some lube points in the illustration will
not be present on other latch systems. (See figure 3)
