Anchor Pattern

4. Wall Anchors

a. Now you are ready to transfer this layout to the wall for drilling. Determine the centerline of

the unit on the wall where you are locating the unit. The width of the wood planks is 66 inches
center to center. (See FIGURE 2)The bottom of the steel frame attachment should be located
9’-10’’ off the finished floor (See FIGURE 1), this will dictate the location of your bottom
hole. Relate this point to your anchor pattern. Mark a centerline of the plank starting at your
bottom anchor location and extending to the top anchor location. Mark the actual hole locations
to each side of the center as they are located on the plank. Try to avoid mortar joints they often
contain wire mesh and are weaker than the surrounding block. The planks may be shifted up or
down slightly to avoid the mortar joints. Avoid attachment in the top 2 to 3 rows of block, this
will cause the blocks to break away.

Important! Remove any sheetrock or other non-structural materials from area immediately behind all
wood planks. This material will interfere with the wall anchors. Failure to remove drywall or other
such material may result in the entire backstop unit falling off the wall.

b. After marking all the anchor locations, double check before drilling. Make certain they are at

the right height, width, and distance apart. If you are over a finished floor, make certain to
protect the area prior to drilling. A box taped to the wall under each hole as you drill will catch
a large portion of the dust. Drill all holes before attaching the planks. See Appendix A –
Anchor Management for specific details on anchor installation.

c. Clean the area thoroughly before proceeding to prevent spreading masonry dust.
d. Determine the proper anchor for each location. This is IMPORTANT. Do not try to use an

anchor that is not suited to the location. For instance, don’t use an expansion anchor in a hollow
wall application. Suitable toggle bolt anchors are available. If you carry a variety to allow for
