INSTALLATION DETAILS-MECHANICAL POWERSTOP
Concrete Dock Face
(Standard installation)
Low Pit Floor
(Distance from pit floor to drive under 24”)
Cantilevered Dock
(For bumper projection >4” or cantilevered dock or Edge-of-Dock leveler)
Anchor pit floor mounting plate (minimum 3/8” x 20”W x 8” D) 
(Part #9414-0056) with four (4) (3/4”x 5 1/4” min.) wedge anchors. 
Weld mounting plate to curb steel and back plate of PowerStop with 
a continuous 1/4” fillet weld. Anchor back plate of PowerStop to 
dock face with a minimum or (4) 3/4” x 5 1/4” wedge anchors 
(Kit#2103-0003).

Weld three sides of PowerStop back plate to the optional 
embed mounting plate (Part #7953-0119) with ten (10) 
4” long 1/4” fillet welds.

Driveway Mount
(Recommended when dock face is unsuitable for PowerStop Mounting)
48”
8” Min.
Driveway mount requires 
attachment to a concrete 
drive greater than 8” 
thick. For asphalt drive, 
pour 48”x48”x8” (min.) 
concrete pad and include 
six (6) 3/4” dowels into 
foundation wall. Then 
proceed with adhesive 
anchors or weld plate 
embed.
Determine offset 
then proceed with 
“Driveway Mount” 
instructions below.
To determine size offset required, take total effective 
bumper projection (bumper size plus any cantilever) and 
subtract 4”.

(Kit #9414-0058)
Install two (2) 1” Dia. adhesive 
anchors into 1-1/8” Dia. x 7” 
deep hole at rear of PowerStop.
Install two (2) 3/4”

Weld method
Properly locate and level the drive embed weld plate (Part#7953-
0059) in the drive approach. Observe Cantilever conditions for 
proper positioning. Weld restraint to embed plate with a 
continuous ¼” filet weld .
Bolt on Method
Properly locate and level the 
drive embed plate 
(Part#9414-0057) in the drive
