Soffit panels can be secured with J-channel – so called because it resembles the letter J. J Channel can be nailed against the house instead of F channel to install your soffit. You can also use two pieces of J channel back to back to to make an “H” channel to secure corners. 12 foot pieces.
This 3/8″ J Channel goes with either the Triple-4 or the Quad-4 soffit panel.
