Spare wire for BiRek, 1.3 mm

What this is

A spare swinging rod for the BiRek tensor. The swinging rod is the middle of the tensor’s three parts: it plugs into the metal handle and is fixed there, and it carries the sensor element at its top. Rods are consumable, and a bent or fatigued rod will not swing cleanly.

Which tensor it fits

The 1.3 mm gauge is the rod for the large BiRek tensor:

• G0601 BiRek tensor, gold-plated, large
• G0603 BiRek tensor, high-grade steel handle, large

Choosing the gauge

Two gauges are supplied: 1.2 mm for the small tensor and 1.3 mm for the large. Order the gauge that matches the tensor you hold.
