Attach footplate
The footplate is the centerpiece of the mount, so correctly attaching it to the surface is critically important.
Step 1 | Locate structural elements
Locate the structural elements (rafters) that will
place the footplate in position to meet all of the
appropriate considerations listed above.
NOTE:
Use a deep-scan stud finder to locate
the rafter/structural elements.
Step 2 | Mark and predrill center hole
Hold the footplate in the center of the rafter and
mark the top center hole. Remove the footplate
and predrill 1/8in. hole on the mark.
Step 3 | Mark and predrill remaining holes
Use a level to verify that the center line of the
footplate, defined by the footplate’s center holes,
is level.
Mark and predrill the bottom center hole.
Mark and predrill the remaining four 1/8in. holes,
one in each outside corner.
Always fill any unused holes with tar-based
sealant.
Step 4 | Secure lag screws
Cover the bottom of the entire footplate with tar-
based sealant.
Secure 5/16 x 3in. lag screws through the top and
bottom center holes of the footplate and the
rafter. Leave these loose enough to level the
footplate.
Correctly align the footplate over the 1/8in. holes.
This will allow correct placement directly over
rafters or trusses.
Install 5/16 x 2in. flanged lag screws in each of the
outside corners. Securely tighten all the screws.
