4X5 film holders

I have a couple of 4x5 film holders where the black clothe-like tape that
allows the bottom of the holder to swing open has torn and needs to be
replaced. I'm hoping someone can guide me to a source where I can buy this
tape to repair these holders. Thanks.

If you can get ahold of the old black cloth electrician's tape, this
will work admirably. Dunno where to get it--is it even still available?
Maybe 2nd-hand stores.

You can also glue any kind of black fabric over the edge, using Elmer's
or equivalent if it's a wooden holder. It needn't be light-tight;
there's a light trap in the little door.

The only reason corrupt Republicans rule the roost in Washington
is because the corrupt Democrats can't muster any viable opposition.

  At one time Calumet had the tape but Robert is right, its
just a hinge, not a light blocker, so any cloth or cloth
tape will work.

Bicycle stores ought to stock black cloth tape. It's used for wrapping
racing bike handlebars. I bought some recently.

Gaffers tape.

I have never had to replace the tape, but I have only been using 4x5 since
about 1975. The original is much like the old "friction tape" that
electricians used to use. Perhaps the reason I no longer see that kind of
tape on the market is because electric codes probably do not permit splicing
wires anymore. You should use it all in one run, and any connections seem to
be made with wire nuts inside junction boxes.

Stuff like duct tape are too thick and I suspect too stiff to use with
pleasure; i.e., they would be annoyingly stiff.

   The problem with "friction" tape, and many other tapes,
is that the adhesive migrates and leaves a gummy border
around the tape. Friction tape is NOT the familiar smooth
plastic electrical tape. I have not seen actual friction
tape for some time.
   Gaffer tape works OK for holders because the adhesive is
specifically designed not to migrate. Note that Gaffer tape
is NOT the same thing is duct tape although they are often
confused. Gaffer tape is intended for temporary fastening of
things on a movie set, it is designed to be relatively
strong but to be removable with as litte damage to the
surface its fastend to as possible. Duct tape is meant for
wrapping air conditioning ducts and has a very sticky
adhesive that spreads and is hard to remove.
   Probably the best solution to replacing the hinges on
holders is to use a thin leatherette plastic and cement it
with contact cement. The material is thin and smooth, both
desirable for the application.

Friction tape isn't used by electricians to much anymore. In fact
the use of even electrical tape is frowned on by electrical inspectors.
To many "bad" practices were getting covered up with layers of tape!
Those that have their hearts set on friction tape can go to a sports
store and get the tape that gets used on hockey sticks. It's been many
years since I played hockey but I don't remember any trouble with the
stuff making a mess like electric tape and duck tape.

I've been using gaffers tape on the hinges. It sticks good and I have a
lot of the stuff and can replace it easily.
