These plastic ring binder mechanisms are unique in their manufacturing and material, however, are primarily used by the same kinds of customers as our traditional letter size metal mechanisms. This includes businesses, such as manufacturing plants, industrial supply, government and military institutions, furniture and fabric stores, and more. They are used to make custom 3-ring binders, as well as for a variety of other unique applications; the limitations of binder spines are really determined by the limitations of your imagination.
Because ring binder mechanisms are just the spine piece alone, they offer a lot of versatility to completely customize your application to your specific needs. Whether you are using them to make custom ring binders, or for more unique binder mechanism crafts, they really aren’t limited by much, giving you complete control.
The plastic on these mechanisms makes them different than most other options, which offers a more distinctive look. To add even more differentiation from basic mechanisms, they also come in four stocked colors, including a deep navy blue, black, medium-dark gray, and off-white / cream. The navy blue mechanism would make a beautiful addition to US Navy ring binders.
They are not made 100% of plastic, and actually feature a metal base. This ensures strength and stability for the mechanisms, so they can withstand the test of time. The boosters on each end make it easy to open the rings without mis-aligning them (which can happen sometimes if you pull the rings open by hand). These letter size mechanisms have 2 holes for binder rivets so you can make a straight and strong bond to chipboard covers, or any other material of your choice.
They work well the standard letter size paper, which is the most common size used in the US, measuring 8 ½” x 11”. Because they are only bound on 11" end, and because they don’t need a machine to bind, you can actually bind any size material that is 11” on the binding edge…so make a calendar that is 11” x 22”, top-bound on the 11” edge, or anything else you can think of. They also have standard hole spacing, so you can punch the holes with any regular 3-hole punch like the ones available here.
The pricing is fairly reasonable per piece when you consider that plastic ring binder mechanisms can be difficult to find, let alone to find them for less than $5 each. This pricing of less than $2 each is made possible because we sell them in full case quantities of 150 mechanisms.
That case quantity keeps the pricing fairly low, however, does eliminate some potential users because we cannot break the cases to sell smaller amounts. 150 mechanisms is the smallest quantity we can sell and is a per-color minimum, so we cannot mix colors to get you a total assorted box of 150.
While the metal base makes them very durable, this does eliminate their potential to be used in prisons and other facilities that have an all-plastic requirement. For these users, we recommend poly case binders, or even simple plastic binding rings or snap lock screw posts.
As is true with all binder mechanisms, sometimes setting the rivets can be tedious or difficult. It requires strength and endurance to do them by hand with the rivet setter tool, which is used by everyone who does not have an automatic rivet setter in their manufacturing plant. Before you buy binder mechanisms, keep this in mind and possibly consider our quality pre-made binders as an alternative.
While there are 4 colors to choose from, which is more variety than any other mechanisms, I still personally feel like there should be more and/or different options. I love the navy and black especially, but would also love to see more variety and brighter (or maybe even pastel) colors. Or even a simple pure white option, instead of just the off-white/creamy color. In addition, they only come in one ring size, which is a 1” round ring that is capable of holding up to 225 sheets of paper, or about a 5/8” thick stack of materials.
THE BOTTOM LINE:
Although limited by the ring size, the multiple color options and fact that they hold standard letter size paper make these plastic binder mechanisms quite versatile. They work well for all kinds of businesses and applications, and are manufactured with a blend of both plastic and metal materials for durability. They are sold in full case quantities only and can sometimes be difficult to bind when doing them without an automatic rivet setter. But they definitely have their place in the custom binder industry, and are most commonly purchased by manufacturing facilities and production plants.
