Installing Anchors In Concrete Decks
Once anchor positions have been determined (see General Instructions,
page 1) you will need to drill holes in the concrete deck at these points to
accommodate LOOP-LOC’s brass anchoring system.
Step 2:
IMPORTANT: Use silicone spray on all anchor inserts, shells and Tamp Tool
before installing. When cover is removed, all anchors must be flushed out with
a hose and re-sprayed with silicone before closing. If this is not done, you may
encounter difficulty when trying to raise inserts in the fall.
Step 3:
Insert brass anchor casing into hole and tamp lightly with Tamp Tool to ensure
tight fit, as shown in Figure 4.
Step 4:
Screw brass insert into casing, as shown in Figure 4.
PAVERS, BRICK OR STONE:
When decks are made with brick,
stone or pavers laid on sand, or on a cement slab, the anchor-in-pipe method
must be used or the cover cannot be considered safe and warranted.
For each anchor to be installed by this method, you will need to use ¾”
inside diameter pipe or conduit. Pipe comes in 9”, 15” & 18” lengths.
Installing Anchors In Other Surfaces
Step 1:
Using rotary drill with 1” bit, if using pipe supplied by LOOP-LOC, or appropriate
sized bit for pipe you are using, drill hole through the deck large enough to
accommodate pipe or conduit at anchor points. Wherever possible, drill between
bricks or pavers to avoid cracking them. Continue drilling in case concrete is laid
under the soil.
Step 2:
Drive assembled pipe through hole into ground until flush, as shown in Figure 5.
Place a block of wood or other material over the end of the pipe before driving to
prevent damage to the anchor assembly.
Step 3:
Screw brass insert into casing, as shown in Figure 5.
WOOD DECK:
If a wood deck is at least 1 5/8” thick, the standard
concrete deck anchoring procedure may be used. If deck is thinner, we
recommend an anchor-in-pipe installation method. Wood Deck Anchor
Flanges may also be used, at the dealer’s discretion, depending upon the
quality, thickness and strength of the specific type of wood at the job site.
Note
: Any synthetic wood type materials that do not meet the above
criteria should utilize the standard anchor in pipe method.
Anchor-In-Pipe:
Follow the instructions for PAVERS, BRICK OR
STONE.
IMPORTANT:
You must use pipe or conduit long enough to
extend into the ground itself, taking into account space between wood deck
and ground (see Figure 6). Pipe must always be inserted into ground for
cover to be considered safe and warranted.
GRAVEL, SOIL, OR PLANTER AREAS:
When anchors are to
be installed directly in any type of gravel, soil or loose ground, you must also
use the anchor-in-pipe method. If more than 35% anchor-in-pipe
installation, in a loose unstable area, the pipe should be set in concrete
footings.
Wood Deck Anchor Flanges
are installed as follows (see Figure 7):
Step 1:
Counter-sink 1½” diameter hole 1/8” deep into wood deck using self-boring bit.
Step 2:
Drill ¾” diameter hole into wood deck - minimum 2” deep.
Step 3:
Insert wood deck anchor flange into hole and tap until top of flange is flush with
wood deck.
Step 4:
Secure flange with 4 wood screws.
Step 5:
Screw brass insert into flange, as usual.

Step 1:
Drill ¾” hole at anchor point 2¼” deep. For best results, it is recommended
that a rotary hammer drill and a long spline bit be used. To maintain con-
sistent depth in all the holes, use tape to mark a point 2¼” from the tip of the
bit, and drill to this point each time.
