Installation Video
Installing a 1/4" Double Expansion Anchor - Drill a 1/2" hole into the concrete using a carbide-tipped bit that meets ANSI Standards B212.15.
- The depth of the hole can be deeper or equal to the minimum embedment depth of 1-3/8" which is equal to the length of the anchor .
- Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb.
- Insert the anchor with its threaded end first into the hole.
- Place the fixture over the 1/4" Double Expansion Anchor, insert a 1/4" diameter bolt through the fixture and into the 1/4" Double Expansion Anchor.
- Use a wrench to turn the anchor clockwise until tight or maximum torque value 5 ft. lbs. is reached.
- Always use proper personal protective equipment per manufacturer's and OSHA instructions.

“Once you use the double expansion anchors on brick, you will always want to use them on brick!
Contractors have used single expansion on much of our brick work, most resulting in cracked bricks.
These are not heard of by most contractors/suppliers in my area, glad I came across Confast!!”
