INSTALLATION INSTRUCTIONS (HOLLOW BASE MATERIALS)
INSTALLATION INSTRUCTIONS (HOLLOW BASE MATERIALS)
DRILLING
1- Drill a hole into the base material with a rotary drill tool to the size and embedment for the required by the selected screen tube size and
steel anchor element (see installation specifications for threaded rod in hollow base material with screen tube supplied by Powers Fasteners).
The tolerances of the drill bit used should meet the requirements of ANSI B212.15.
• Precaution: Wear suitable eye and skin protection. Avoid inhalation of dust during drilling and/or removal.
HOLE CLEANING ( BLOW 2X, BRUSH 2X, BLOW 2X)
2X
2- Starting from the bottom or back of the anchor hole, blow the hole clean with a hand pump (min. volume 25 fl.oz. supplied by Powers
Fasteners) or compressed air nozzle a minimum of two times (2x).
2X
• Determine the wire brush diameter (see installation specifications) and attach the brush with adaptor to a rotary drill tool or battery screw
gun. Brush the hole with the selected wire brush a minimum of two times (2x). A brush extension (supplied by Powers Fasteners,
Cat #08282) should be used for holes drilled deeper than the listed brush length.
• The wire brush should be checked periodically during use. The brush must be replaced if it becomes worn and does not come in contact
with sides of the drill hole.
2X
• Finally, blow the hole clean again a minimum of two times (2x)
• When finished the hole should be clean and free of dust, debris, ice, grease, oil or other foreign material.
PREPARING
3- Check adhesive expiration date on cartridge label. Do not use expired product. Review Safety Data Sheet (SDS) before use. Cartridge
temperature must be between 23°F - 95°F (-5°C - 35°C) when in use unless otherwise noted. Review gel (working) time and curing
time table. Consideration should be given to the reduced gel (working) time of the adhesive in warm temperatures.
• Attach a supplied mixing nozzle to the cartridge. Do not modify the mixer in any way and make sure the mixing element is inside the nozzle.
Load the cartridge into the correct dispensing tool.
• Note: Always use a new mixing nozzle with new cartridges of adhesive and also for all work interruptions exceeding the published working
time of the adhesive.
h ef
4- Prior to inserting the anchor into the filled screen tube, the position of the embedment depth has to be marked on the anchor.
Verify anchor element is straight and free of surface damage.
3X
5- Adhesive must be properly mixed to achieve published properties. Prior to dispensing adhesive into the drilled hole, separately dispense at
least three full strokes of adhesive through the mixing nozzle until the adhesive is a consistent GRAY color. Do not attach a used nozzle
when changing to a new cartridge.
• Review and note the published working and cure times (see gel time and curing time table) prior to injection of the mixed adhesive into the
screen tube.
INSTALLATION
6- Select a screen tube of suitable length (supplied by Powers Fasteners). Fill the screen tube full with adhesive starting from the bottom
or back of the tube. Slowly withdraw the mixing nozzle as the screen fills to avoid creating air pockets or voids. A plastic extension tube
supplied by Powers Fasteners must be used with the mixing nozzle if the back of the screen tube cannot be reached.
7- Insert the screen tube filled with adhesive into the cleaned anchor hole.
8- Prior to inserting the anchor rod into the screen tube inspect it to ensure that it is free of dirt, grease, oil or other foreign material.
• Push the threaded rod into the screen tube while turning slightly to ensure positive distribution of the adhesive until back of the tube is
reached.
CURING AND FIXTURE
e.g.
68˚F
45
mins
9- Allow the adhesive anchor to cure to the specified full curing time prior to applying any load.
• Do not disturb, torque or load the anchor until it is fully cured (see gel time and curing time table).
T max
10- After full curing of the adhesive anchor, a fixture can be installed to the anchor and tightened up to the maximum torque (see installation
specifications for threaded rod in hollow base material) by using a calibrated torque wrench.
• Take care not to exceed the maximum torque for the selected anchor.
