Step 2: Mount Wall Plate

Wood Stud Wall

The wall plate must be mounted to two wood studs. 
Use a stud sensor to locate the two studs, clearly 
marking the outer edges of the studs (see Diagram B). 
Use a long level to ensure the two holes are level at 
the desired height. 

Pre-drill two upper holes in the center of your studs 
and attach the wall plate to the wall using 2 lag bolts 

(I)

 (see Diagram B). Do not overtighten lag bolts 

(I)

. Make sure the wall plate is flat against the wall 

surface. Using the wall plate as a template, pre-drill the 
bottom 2 holes, and secure using 2 lag bolts 

(I)

, taking 

care not to overtighten.

Brick or Concrete Wall

Using the wall plate as a template, mark four holes 
toward the outer edge of the wall plate at your desired 
height (see Diagram C). Adjust the wall plate position to 
be clear of mortar joints, keeping in mind that the mount 
provides minor horizontal shift along the length of the 
wall plate. Use a long level to ensure the four holes are 
level and at the desired height. 

Pre-drill four holes, and insert a concrete anchor 

(J) 

into 

each of the holes flush with the concrete wall surface 
and not flush with the surface covering, such as drywall. 

Attach the wall plate using 4 lag bolts 

(I)

 (see Diagram C). 

Make sure the wall plate is flat against the wall surface. 
Do not overtighten lag bolts 

(I)

.

CAUTION

 

 

Make sure the supporting surface will support  

the load limits outlined in the caution at the bottom  
of page two. Tighten lag bolts until the wall plate is 
snug flat against the wall. Do not overtighten lag bolts 
(I). Each lag bolt must be located in the center of a 
wood stud.

CAUTION 

Make sure the concrete or brick wall is at least  

2.5” thick. Make sure the anchor is seated completely 
flush with the concrete surface even if there is another 
layer of material, such as drywall. If drywall is over 5/8” 
thick custom lag bolts must be used. Concrete must be  
a minimum of 2000psi in density.
