7mm (9/32") Silver Spiral Plastic Coils [12" Long, 4:1 Pitch, 47 Sheet Capacity (approx)] (100/Box)
These 7mm spiral coils (9/32") will bind up to about 47 sheets of 20 pound bond paper, or about a 3/16" thick stack of pages. They are a silver color, which offers a gray that has a touch of shimmer to give it a metallic-like look. They have standard 4:1 pitch hole spacing for perfect compatibility with any 4:1 pitch coil binding punch machine. These coil binders are 12" long for standard letter size pages measuring 11" on the binding edge; the extra 1/2" on each end is essential to allow for cutting/crimping-in of the ends. The plastic material makes them flexible, durable, and perfect for personal, education, or professional document bindings of all kinds. These spiraled binder spines are packaged with 100 coil spines per box.

I RECOMMEND THIS FOR:
Spiral coil binding is the ideal choice for anyone who needs a durable and flexible binding spine. For users such as those who may travel with their bound documents on sales calls, or go to conferences across the country, coil bindings are a great choice because they are durable enough to withstand handling and packaging without being damaged (but be sure to protect your pages properly with report covers). They might not be the best choice for high-end presentations, though, because some users feel that the plastic is not very professional; but if durability, longevity, and ease-of-use are important to you, then plastic coil binding might just be the best bet.
HOW COIL COMPARES TO OTHER BINDINGS:
When talking about punch-and-bind solutions, coil binding is often what people first picture in their minds. In fact, spiral coils are the most popular way to bind presentations and books within a business across the board. But with that in mind, let’s compare some of the functions and features of coils with other popular punch-and-bind options, so you can more accurately gauge which one will be the best choice for your individual needs.
|Binding Type||Spiral Coils||Wires||Combs|
|Largest Book You Can Bind*||1 ¾" Thick Stack|
About 440 Sheets
(With a 50mm Coil)
|1 ⅛" Thick Stack|
About 260 Sheets
(With a 1 ¼" Wire)
|1 ⅞" Thick Stack|
About 425 Sheets**
(With a 2” Comb)
|Part of the reason why coil bindings can hold more capacity, even compared to larger alternatives, is because they are a continuous loop of plastic. Wires are metal (which doesn’t have the same bounce-back) with loops that protrude into the holes, and combs have prongs or teeth that tuck under the spine. The continuous coil is stronger and can hold more pages, without worry about them falling out.|
|Damage when Bent||No||Yes||Yes|
|Color Choices||White, Black, Maroon, Red, Clear, Blue, Navy, Forest Green|
+ many special-order colors, including (not limited to) purple, pink, yellow, orange, baby blue, teal, leaf green, gold, charcoal, brown, pearl white, & more

WHAT I LIKE ABOUT SPIRALS:
As mentioned above, the most notable feature of coils is their durability. But if you’re asking me for my personal favorite thing about them...well, I would have to say it is that they make fun cat toys. Check out my cat, Shadow in this coil video at 0:14 in her moment of fame (supervised play only, IMO). In more seriousness, though, coil bindings are truly a staple in the industry. Preferred by the majority of businesses, they are simple, they look nice, and they’re tough.
I also love the huge variety of colors and the fact that, even the more unique special order colors, can be produced quickly, making them more accessible for any company, even those on a more strict deadline. The many colored coil options make it easy to brand-match them to your logo, your client’s business, or the theme of your specific presentation.
THINGS TO CONSIDER:
The reason for choosing options other than binding coils is nearly always the “cheap look” of the plastic. But that refers simple to the fact that the material is plastic, not to the thickness or make of the plastic. In fact, the plastic filament used to make coil bindings is quite thick, and this falls more to a color choice. For example, the black and clear are my favorite stocked colors precisely because of the fact that they look professional (and the pearl white special order; so gorgeous!). Something else we sometimes hear is that the bind process takes too long; customers who need something fast should consider some document binding solutions that don’t require punching at all, such as thermal binding or tape binding. And lastly, some users feel that it is too difficult to roll in the extra long coils through the many holes on a binding edge (usually 43 or 44 holes); those users would benefit from adding an electric coil inserter (preferably one with adjustable rollers) to drastically increase the speed and efficiency, virtually eliminating any stress. And even with all of these “negatives” or reasons why someone might choose a different binding over coil, our spiral binding still have an all 5-star rating, and remain our best selling binding supply.
THE BOTTOM LINE:
Spiral binding is awesome. That’s the bottom line!
* Approximations. Sheet capacity based on 20# bond copy paper. | ** Although the comb is larger, you will notice the sheet capacity is less. That is because of the weight of the paper sheets; too many pages will be too heavy for the comb prongs to hold. | *** Clearance colors, available in select sizes, while supplies last.
