Pre-Fab Loop with 10' lead-in wire for New Construction. Rated at 125 uH, +/- 6.25%
They're made out of 6 turns of a single 18 AWG wire and include an 18" piece of PVC to protect the wire to the conduit.
We also use these in some retro-fit applications where the road surface is too unreliable for a regular retro-fit saw-cut loop (encapsulated wire).
