New Magnet Sign Revealed

CIMG1097 CIMG1098 CIMG1099 CIMG1101 CIMG1103 CIMG1104

After a customer requested a magnet sign with a hinged front cage, we had to evaluate whether we wanted to take the challenge.  We have made magnet signs for various customers, but we were hesitant to build a magnet sign with a cage.  Although the patent for magnet signs kept us from doing this in the past, we were also concerned about creating a design that would allow the weight to be properly distributed over the sign.

After agreeing to build the sign, there were a variety of factors that went into the design.  We chose to use very common hinges and material when building the screen.  We didn’t want the sign to be so overwhelming that it could not be built by whoever wanted to start their own magnet sign rental business.  (Please confirm by your own research, but the patent on the magnet signs is very near [or has] expired at the time I am writing this.)  When the blueprints for the sign are available, they will be available to be purchase or as part of a letter package.

Interested in building your own rental signs OR considering letting us build them for you?


Specifications On Our Fluorescent Vinyl

The vinyl we use outlast any other vinyls we have tried.  It does cost more, but we believe its life span makes its cost well worth it.

We do stock 5 of the 6 standard colors:  (We do not stock the blue.  If requested, for a large enough order, we could also stock.  The fluorescent blue is really to dark to show up well on black, but it would work on white coroplast.)

  • Yellow
  • Pink (Fuchsia)
  • Red
  • Orange
  • Green




The Neons are a high performance cast vinyl fluorescent film series providing dynamic graphic accents for indoor and outdoor uses.

Plastic Letter Sizes



Over the years, a variety of sizes of black sign letters have been made.  The above image packs in LOTS of information.

  1. There are basically “two” sizes of letters.  There are the 8 inch (7 7/8″ letters and the 16″ letters which are approximately double the size.  The 16″ letters take up twice the height of the 8″ letters while “skipping” the track.) and 10 inch.  (Same as the 8″ letters, but the letters are 10″ and 20.5″.)
  2. When the letter sets are created, there are 3 sizes of coroplast that are needed.
    • The “R” size is used by almost ALL of the letters and most numbers and most symbols.
    • The “I” is used for one letter/number and a couple of symbols.
    • The “M” is used for only the M.  It is our widest letter.
  3. There is also a 4″ and a 5″ letter set on the list.  Those were used for our sidewalk signs and banners.  Unless your our TOTALLY duplicating our business, it probably won’t be of much need to you.
  4. On the image with the letters, the contrast is seen between the size of the letter panel and the actual letter.  (The letter panel is the piece of coroplast the letter is attached to.  The letter is the vinyl letter attached to the coroplast.)
    • On the 20 inch letter [actually 20.5 inches tall], the letter is 18 inches tall.
    • On the 16″ letter, the letter is 14 inches tall.
    • On the 10″ letter, the letter is 9 inches tall.
    • On the 8″ letter [actually 7 7/8 inches tall], the letter is 7 inches tall.

There is more of this detailed stuff to post, but hopefully this gets us a common set of terminology.

Patent Issues

The question often asked, “Will I get sued if I build my own signs?”  A few years ago, the question might have been answered “yes”.  Now, however, both patents are nearing the end of their lives.  So, feel free to sort out the details yourself.  (I am not giving legal advice on what you should do.  Please review the patents and make the decision you think is best.  What I am saying is, “If it were me, I would not worry about the patents I might run up against.”

The links for both the black sign and magnet sign patents are listed here:

More Permit Issues

In some cities, they charge you a yearly fee to register to be able to get permits.  In Fort Worth, I believe this is $120.  (Hopefully, this is cheaper where you are at.)  Another town I have signs in does not charge any type of registration fee.

Without the registration, you can’t pull a permit for a rental sign.  So, it basically forces customers to rent signs and not purchase them.  If they purchase signs (in Fort Worth for instance), they could only put their sign out every other month.  However, there does seem to be a gray area when the sign is for a non-profit.  (Apartment complexes also seem to have some different rules.)  Regardless of anything I am writing here, it is VERY beneficial for you to pick the brain of someone who knows how sign rentals work in your local area.

So far, it appears the applications can be done via email.  Typically, their is an application and some type of map needed (Google maps and a graphic program) should set you up pretty well.  As long as you have a scanner/fax, you should be able to get most of this process done.  You may need to pay the fee via a website OR they will charge your credit card directly.  If all seems to work out.  (There was the time I received an email where I was charged for an unaccounted for amount.  It turned out to be a rather unsophisticated copy/paste with an email address-I got someone else’s email.)

If required, the permits are just a necessary evil.  If the customer’s have rented from someone else before, they know how it works.  You provide them an invoice with your sign rental charge and the sign permit fee on a separate line.  If you are going to do this, the paperwork is a part of the process!

Are Portable Signs Allowed In My City?

The answer to this question is critical before you invest much in your portable sign rental business.

In the Dallas-Fort Worth area, the answer is mixed.  In Dallas, you are not supposed to have portable signs.  In Fort Worth, you are allowed to have signs with a permit.  Their are wrinkles to these rules though.  Some customers will choose to buy signs to use in areas where signs are not permitted.  They will put the signs out during the day, and they will bring them in at night.  If their business is in an area not often frequented by the sign inspector (or in a non-sign area, any public official who cares about such things), they might be completely okay using this method.  (I am told their are some areas on the outskirts of Dallas where this is the case.

To find out whether your city OR any of the nearby cities will allow permits, you can probably go to the cities website.  Their is usually a contact for permits or inspector.  If you give the phone number a call and ask for the correct person, you will probably have a pretty definitive answer.  If yes, you probably want to go ahead and ask if their are any fees to get a sign permit.  If “no”, you probably don’t want to read off of a list of “offenders” in that city.  It probably just means the city officials don’t keep a very close tab on things.

In the cities I have placed signs thus far, the fees have run from $10 to $75 per month.  A couple “cities” (more accurately 2 mile stretches on a particularly heavily traveled road) have no fees and no restrictions.  Restrictions?  Yes, some cities get into this as well.  Some allow one month of displaying a sign with one month off.  Others allow 2 months on, and one month off.  While the inspectors may not hold you to an exact 30 day month, it is best to stay on their good side.

Have you seen any other variations on fees, display options or anything else described here?  Please let me know!

Ten Inch Letter Sets



Recently, we had a little confusion with a customer.  They ordered our 10 inch letter set.  (Our letter panel is 10 inches, and the actual letter is 9 inches.  Our 8 inch letters have a panel of 7 15/16th inches with a letter of about 7 inches.  The 16 inch and 20 inch letters work out similarly.)  After they received our letters, we received an email back from them saying, “They don’t fit.”  Once they sent a sample of their existing letter set, it all made sense.

Our letter sets are made with black coroplast and a heavy duty fluorescent vinyl.  The black letter panels are cut to the correct size and the plotter-cut fluorescent vinyl is applied to the letter panel.  (See the smaller “N” above.”)  Another way of providing similar letters involves using a printer.  The letter above on the right is done on a printer.  It is printed on white coroplast.  The letters I sell are the letter sets developed by the gentlemen who held the black sign patent. (#6,108,955)

Bottom Line:  Both letter sets will work, but do to the printing process, the vinyl letter is likely to take a longer time to fade.  (Possible lasting 3 or 4 times longer)  SignsSeen can do different fonts on our letters sets.  If you are interested, please contact us!
