[BC] Guy line part name

[Mike McCarthy]

Hey brain trust...

I'm having a brain freeze on a specific guy line part. It resembles a
shackle, but is really a bent omega loop of 1/2" bar with outward bent
loops on each end.  The opening is closed by a 2nd 1/2" bent rod which has
nuts on either end.

This device is often used tying smaller diameter guy lines to a johnny
ball and on utility guying systems.

Anyone recall the name of this device and a vendor with stock?  I need 6. 
My usual suppliers don't have any and can't recall the "trade" name
either. But they know to what I'm referring.

Thanks...

MM
