Anchor Bolt Adaptor

Light Pole Systems' Anchor Bolt Adaptor (ABA) was designed to fix the common problem of anchor bolts not matching the light pole. This problem most occurs when anchor bolt circle is confused with anchor bolt square, the wrong anchor bolt template is used, or if the pole base plate is cut incorrectly. The ABAs threads onto the existing anchor bolt, in place of the leveling nut and washer, and the light pole is bolted to the ABA studs with the included nut and washer. The Anchor Bolt Adaptor allows the bolt circle to change size, rotate, or move center.

Anchor Bolt Pattern Adjustment Options

The anchor bolt circle can be adjusted by up to ABA.75: 4.4 inches, ABA1&1-.75: 5 inches, larger or smaller


If the anchor bolts are not centered in the footing the Anchor Bolt Adaptors allows for up to

 ABA.75: 2.5 inches, ABA1&1-.75: 2.5 inches of lateral movement. 

If the anchor bolts are not clocked correctly, the Anchor Bolt Adaptors can rotate the pole on the footing. The amount of rotation depends on the diameter of the bolt circle.






 If each anchor bolt needs a different adjustment, the individual blocks can be set in a different position.
