Model 1280 (A-6)

The Model A-6 Flexible Rod Extensometer uses continuous lengths of fiberglass rods (inside protective tubing), cut to customer-specified lengths, coiled at the factory and shipped ready for installation. The extensometer is lightweight, making it easier to handle for installation and less costly to ship. On-site assembly time is minimal and the installation procedure is simplified.

The Model A-6 has been replaced by the Model 1100 Rod Type Borehole Extensometer.
