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.
