Option 1    (soft ground) 
 
Slide one 16” steel L-channel ground anchor 
into bottom of each post.  Slide ground anchor 
up to bottom cross rail.  Using two 1” self-
tapping white-head screws per post, screw 
post to ground anchor (figure 1).  When 
fastening, use one screw per side where 
ground anchor meets post.  For added support 
fasten screws with at least two inches vertically 
between them. 
 
Option 2     (hard ground) 
 
Measure distance between posts and mark 
ground accordingly.  Pound 16” steel L-
channel ground anchors into ground according 
to measurements and basic layout (figure 2), 
leaving about 4 inches of ground anchor 
exposed.  When pounding into ground, use 
block of wood to prevent ground anchor from 
bending.   
 
Slide trellis over ground anchors.  Using two 1” 
self-tapping white-head screws per post screw 
post to ground anchor (figure 1).  When 
fastening, use one screw per side where 
ground anchor meets post.  For added support 
fasten screws with at least two inches vertically 
between them. 
 
Option 3     (permanent installation) 
 
Measure distance between posts and mark 
ground accordingly.  Dig holes 12” deep 
according to measurements and basic layout 
(figure 2).  Fill with cement and place 16” steel 
L-channel ground anchors in wet cement.  Be 
sure that ground anchors are straight and in 
accordance with measurements of trellis posts.  
Allow cement to dry.  NOTE: There is very little 
room for error with this installation method.
