Mag-Daddy MD62409-5 Cable Daddy Black Round Fastener, (Pack of 5)

I bought these to keep some temporary wiring for a wide-band O2 sensor neat and off the ground while I set up the jetting on my V8 Falcon. The magnets are strong and they work as they should.

Broke the first time I used them. Trying to push RG8 coax into one, broke the wing off.
