Step 1:  TRUCK-PREP BEFORE MOUNTING GATE 

1.  Carefully check dimensions given on page 5.  Verify you have the proper space 

available to mount the gate.  24-1/2” represents the standard mounting height.  
For a bed height of 44”, this mounting height will yield 10” ground clearance 
(unladen). 

 
2.  If more ground clearance is required, or the bed height is less than 44”, the 24-

1/2” mounting dimension can be reduced.  For every 1” reduction in the 24-1/2” 
dimension, you will need approximately one additional inch in clearance between 
the door sill and truck chassis (beyond the 28” minimum dimension).  Example: if 
the mounting dimension is reduced to 22-1/2”, you will need approximately 30” 
between the door sill and the truck chassis. 

3.  Once it is clear, the proper space is available for gate installation, the door sill 

must be notched per dimensions on page 7.  It is important the sill be reinforced 
after notching using gussets as described on page 7.  The sill must be strong 
since it serves as the “up” stop for the gate. 

Step 2:  MOUNTING GATE TO TRUCK (SIDE DOOR) 

1.  Unfold the secondary platform. 
 
2.  Clamp the secondary platform to the lift truck approximately centered (see 

illustration on page 8). 

3.  There are two angles in the shipping kit (5 x 3 x 1/4 x 3 lg.).  Lay these two 

angles on top of the door sill to space the platform out 1/4” (see sketch on page 
8). 

4.  Pick up the gate assembly.  Position it at the door opening as required and push 

it against the sill and the 1/4” spacers.  With two pieces of scrap channels or 
angles, clamp platform flush with floor.  Use four clamps.  Clamp channels to sill 
and platform.  Flat area of platform farthest away from truck should be 1” higher 
than door sill to allow for platform deflection under load.  Step 16 on page 11, 
explains how to use the shims provided to adjust platform slope. 

5.  With a floor jack and piece of 4 x 4 wood, swing and raise the main tube until it is 

at the 24-1/2” standard dimension – or a reduced dimension if needed.  With a 
pipe wrench rotate the main 4 x 6 trunion tube, so it is vertical.  You should see 
approximately 3/8” of exposed rod on the cylinder if you used the standard 24-
1/2” mounting height.
