Item #: RINGMECHSPLA-GRP

Be the first to review this product

Our three-ring plastic binder mechanisms come in a 1" round ring size and are available in either black, blue, gray, or off-white. Plastic ring binder hardware is sized for standard letter size 8 ½" x 11" paper and features two boosters to allow for easy ring opening and closing. With traditional 4 ¼" spacing between these rings, they can be used with any standard 3-hole punch. Although made primarily of a thick, durable resin plastic, the backing of these ring binder parts is made of metal for added stability and strength. They work great for anyone who is looking for the convenience of a 3 ring binder mechanism, but wants a different look and style than traditional metal 3 ring mechanisms. You can use them with binder rivets and a rivet setter tool to make your own ring binders, or use them to make swatch books or for other crafts. Plastic binder spines offer a unique alternative to traditional metal spines, and are sold in cases of 150 pieces. Buy letter size 3-ring plastic binder mechanisms online today.

Plastic Mechanism FAQs

Q: Are these made completely of plastic?
While the facing, rings, and boosters are all made of a hard plastic, the backing is made of metal. Some all-plastic alternative options include plastic loose leaf rings, plastic screw posts, and case binders.

 

Q: Do you have more ring sizes?
Plastic ring mechanisms are only manufactured with a 1" ring at this time. If more sizes are available in the future, they will be added to this page.

Product Description

If you've been searching for plastic ring binder spines, you've come to the right place! Binding101 stocks a selection of plastic binder mechanisms in several colors, including black, gray, off-white, and blue. The plastic is not flexible; it is a thick and durable resin that can withstand heavy usage. For added durability, the backing is made of metal.

The rings on these binder spines are 1" in diameter, which is rated to hold approximately 225 sheets of standard 20 lb. copy paper, or about a 5/8" thick stack of materials. They feature three rings that are spaced 4 ¼" apart from each other, which is the standard US spacing for letter size 8 ½" wide by 11" high paper. That means you can use them with any of our standard 3-hole punches, and pair them with full size index tabs.

Whether using these unique plastic ring hardware pieces to make unique custom binders, or for journals and notebooks, they make a great choice for anyone who wants the functionality and strength of traditional 3-ring letter size binder mechanisms, but with a modern twist. Consider using them with binder rivets and a rivet setter tool to attach them to material of your choice.
