Pro-Tape aka Pro-Gaff Tape fka Permacel

Pro-Tape used to spool Permacel P-665 and P-672 Gaffer Tape onto their cores under the name Pro-Gaff, Permacel P-665 and P-672. Shurtape bought Permacel Arts and Entertainment Division (including P665 and P-672 Gaffer Tape), and discontinued all of the colored P-665 and P-672, keeping only black, white and grey.

With that said, Pro-Tape aka Pro-Gaff markets their own gaffer tape. Shurtape markets their Black, White, and Grey gaffer tape as Shurtape P-665 and P-672. Clear as Mud? (Filmtools is also disappointed.)
