Required Tools: 3/16 drill bit, 1/2" Masonry Bit for brick concrete or concrete block installations, 1/2" wrench or socket, Phillips screw driver.
Supplied Parts:
(1) Wall Plate - a
(6) 1/4 x 2.5" Lag Bolt - e
Mounting the Wall Plate: Wood Stud, Brick, Solid Concrete, and Concrete Block mounting options are provided.
1a] Wood Stud mounting: The Wall Plate (a) must be mounted to two wood studs at least 12" apart. Use a high quality stud sensor
to locate two adjacent studs. It is a good idea to verify where the studs are located with an awl or thin nail shown in Diagram 1-A. Pre-
drill a 2.5" deep hole at the desired height in each stud using a 3/16" drill bit. Make sure these holes are in the center area of the studs
and level with each other . Use the Wall Plate as a template to mark the location of the second hole in each stud. Drill 2.5" deep holes
using the 3/16" drill bit in the marked locations. Attach the Wall Plate to the wall using four 1/4 x 2.5" Lag Bolts (e) and four Lag Bolt
Washers (d). Make sure the Wall Plate is oriented so the fl at surface in the center of the plate is against the wall and that a set of Lag Bolts
is on each side of the two large holes in the center as shown in Diagram 1-B.
Diagram 1-A
1b] Brick, Solid Concrete and Concrete Block mounting: Use the Wall Plate (a) as a template to mark 6 hole locations on the wall.
The outer holes must fall to left and right of the two large holes in the middle of the plate. Three in the top row of slots and three more in
the bottom row. Make sure these holes are level and there is at least 6" between any two holes. Pre-Drill these holes with a 1/2" masonry
bit to at least 2.5" in depth. Insert a Concrete Anchor (e) into each of these holes. Make sure the anchor is seated completely fl ush with
the concrete surface even if there is a layer of drywall or other material in front. Attach the Wall Plate to the wall using 6 Lag Bolts (e)
and 6 Lag Bolt Washers (d).
