| DESCRIPTION
/ SUGGESTED SPECIFICATIONS |
Expansion
Type Anchors—
SPECIFIED FOR ANCHORAGE INTO CONCRETE
The Boa™ Coil is a high performance expansion
anchor providing through fixture fastening and easy removal to keep
the job moving. It’s reusable with the coil replacement anchors
making this anchor a low cost solution.
Ideal combination of value, performance and
reusability make the Boa Coil the choice for Forming and tilt-wall
contractors.

| INSTALLATION
STEPS |
|
|
| NOTE: To achieve maximum loads the installation
process needs to be carried out as follows: |
| 1. |
Using the fixture as a template, drill the correct
diameter and depth hole. |
| 2. |
Remove debris with vacuum or hand pump. |
| 3. |
Insert the assembled Boa Coil anchor. (The coil anchor tab points
up the anchor.)
Tap anchor down to depth set mark and stop. |
| 4. |
Tighten until washer is firmly held to the fixture and stop.
Number of turns to set anchor: 1/2" 3-4 turns, 5/8" and
3/4" 4-5 turns. Ensure washer is tight and snug fit. |
| 5. |
The Boa Coil anchor is
ready to take load. (The bolt can be removed leaving the coil in
the hole.) |
| The Boa coil
anchor can be reused up to 3 times in new holes. |
