Chance Helical Pole Supports are used with SS5 or SS150 Square Shaft anchors to help prevent a direct buried pole from sinking in soft soils. Support installs in the bottom of the pole hole.

Hot-dip galvanized per ASTM A153.

• Saves time and money.
• Installs in minutes with Standard PISA® or Tough One® anchor drive tools.
• Auger standard size pole hole - unlike oversize hole for pole bearing plates.
• Less spoils to remove.
• Greener method than expanding foam!

Bearing capacity can be estimated using soil class or calculated by measuring torque. The bearing capacity is shown below for SS5 and SS150 anchors (40,000 lb. maximum). For example a 100-foot Douglas fir pole weighs approximately 10,000 lb.. which can be supported in a class 7 soil by an SS5 Lead Section with 8" and 10" helix plates.
