Mounting Directions
WARNING! These drawers are rated to hold a maximum of 400# evenly distributed. The enclosure is rated to

hold 2000# on top evenly distributed. This would include any dividers mounted in the drawer. Never stand or sit
on the Tuffy drawers or enclosure. The vehicle should not be operated with the drawer(s) opened and not
secured shut. The drawers should not be operated/opened when not level. Keep hands clear of moving parts
and pinch points when maneuvering the drawers. Do not exceed the rated weight capacity for this product.

FOR SAFETY THE DRAWER REMOVAL REQUIRES AT LEAST (2) PEOPLE. THE DRAWERS SHOULD ALWAYS
BE EMPTY BEFORE REMOVING IT. CONSTANT SUPPORT MUST BE APPLIED TO HOLD UP THE FRONT OF THE
DRAWERS THROUGHOUT THE ENTIRE REMOVAL PROCESS SO IT DOES NOT CAUSE INJURY AND/OR
DAMAGE.

1. Check the truck bed and wheel well panels of the vehicle for cubby holes containing important gear or require access
in an emergency (Jack, spare tire, spare tire access, fuses, etc.). Remove and relocate any inaccessible items as
required.

2. Remove drawers from enclosure. Pull each drawer out until it stops. Lift up the front of the drawer and pull it out a
few inches further until the stop bolts on the drawer slides clear the rollers on the enclosure slide. Pull the drawer
again until it stops being sure to support the front of the drawer. Pivot the front of the drawer down and lift the rear
end of the drawer out so the rollers on the drawer slides pull free through the slots in the enclosure slides. Repeat for
the remaining drawer(s). Reverse steps to install. (See Figure 1)

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)
