3. Drilling of Wood Planks

a. The wood planks for attaching to the wall are predrilled for their specific brackets. Lay these

out on a sawhorse or similar work area. You will need to drill them for anchor bolt locations.

b. It is best to use ½” anchors for the wall, therefore a ¾” hole in the wood plank is desirable to

allow for leveling the plank. Set up a drill with a ¾” wood drill bit.

c. When marking the planks, mark and drill from the front of the plank, the side facing away from

the wall. This will be exposed as a finished product, so mark lightly. You need to drill from this
side in order to prevent splintering when drilling

d. Pulley and chain attachments are mounted to 96” planks. These are critical attachments, 8

anchors per plank are required.

e. Stagger the anchors from side to side leaving 2” of wood outside each anchor and ultimately

using 8 anchors for the plank.

f. It is very important that these holes are drilled as straight as possible through the planks,

otherwise it becomes difficult to level them.

4. Wall Anchors

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

the unit from the drawings and architectural drawings. Determine the width of the frame from
your installation drawings. The bottom frame attachment is indicated on your drawings, 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.
Continue marking pulley and/or chain locations. These points may also be shifted slightly to
obtain desired anchor locations. 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
different applications, you will save yourself a huge amount of time and trouble, and do a better
job at the same time. If you use a double expansion anchor, make sure you use a back-up
washer between the wall and plank to prevent the anchor from pulling into the wood. Use a
suitable washer at the face of the plank to cover the hole. 1-1/2” outside diameter works well.
