Anchor Heads

1-3/8”  and 1-1/2" square hub anchors are installed using a Kelly Bar adapter and Torque Tube to apply torque directly to the anchor’s square hub. They are commonly used with a 7’ anchor rod and single, double, or triple eyenut. Extensions for the Torque Tube and anchor rod are available when deeper installation depths are required. Final installed height of the exposed anchor should be 8 to 12 inches above grade level.

Install 2-1/4" and 2-1/2" Turbo Drive Anchors with high strength installation tooling (7-5/8” bolt circle). Turbo Drive anchors are installed using a Kelly Bar adapter and Torque Tube to sleeve into the anchor and apply direct torque. They are commonly used with a 7’ anchor rod and single, double, or triple eyenut. Extensions for the Torque Tube and anchor rod are available when deeper installation depths are required.

Standard Turbo Drive (TD) anchors have a 3/8” thick helix. Heavy duty Turbo Drive (TDH) anchors have a ½” thick helix.

Description

A complete Power Hub Screw Anchor assembly consists of a helical hub, anchor rod and eyenut.  The helix size (diameter) and number of helices are selected for the required holding strength.  The hub, either socket drive or solid hub, is selected for installation torque requirement.  The rod diameter is determined by the guy load and installed depth, and eyenut for the number of guys.
