Concern:
Light poles are secured to their concrete foundation using four anchor bolts. The rods on which they will be threaded must be aligned exactly or the metal base of the pole will not fit onto them.
The rods must be lined up beforehand but may accidentally move when concrete gets placed and vibrated.
Countermeasure:
Secure spacing before installation.
The jig secures the four rods in place relative to each other.
Limitation:
| Triz Description | 24.1: Use an intermediary carrier article or intermediary process. |
