    i did see a bundle of short ones designated for a company that sells portable lighting systems, but nothing else that I remember.
    When I did resi up grades I was taught to always assume that all grounding, electrical and telco, was inadequate unless verified.

    I never verified crap, just supplemented with code legal options and left the other stuff as auxiliary and not subject to code mins.

    Actually, they're copper-clad. If you look closely, you can see that the copper is spirally wrapped.

    And I use them all the time.

    Even plain zinc coated (galvanized?) 1/2” rods are legal if listed.

    I bought some LFMC at the supply house today, it was non-UL listed. They started selling a bunch of generic off-brand stuff lately.

    Yup, if it's a 5/8" rod no listing required, 1/2" required. It can even be a piece of 3/4" RMC.

    The one at Lowes are 1/2" and are listed

    Here is what the code states

    Rod-type grounding electrodes of stainless steel and
    copper or zinc coated steel shall be at least 15.87 mm (5∕8 in.) in
    diameter, unless listed.
