Two FeCrAl wires twisted together and wrapped Clapton style. Pack of five or ten 120mm (4.72 inch) wires. These are relatively thick wires, so make sure your atty has post holes large enough to accommodate them.

Size options:

• 32 gauge around 2 x 22 gauge twisted wires
• 32 gauge around 2 x 24 gauge twisted wires 
• 32 gauge around 2 x 26 gauge twisted wires 
• 32 gauge around 2 x 28 gauge twisted wires 
• 38 gauge around 28 gauge, then twisted

What's the difference between FeCrAl and Kanthal?
