3:1 Pitch 12" Plastic Coil (100 pcs/bx)
Create an impressive presentation with these colorful binding spines. Color coil adds energy to your reports and proposals, and demands attention. This spine always keeps its shape with bounce-back flexibility. It lets pages lie flat with 360 degree rotation for convenient note taking and photocopying. Its bind is permanent, so you can be sure documents stay organized. To determine the coil size for your document, measure the thickness of the document sitting on a flat surface and add 2 mm.
These coils are 3:1 pitch (meaning they have 3 holes per inch of your document). 3:1 is a bit of a specialty size meant specifically as an alternative to Twin/Double Loop Wire Binding and GBC Proclick. This size is easier to use for large diameter books because there are less holes to run the coil through. Also available are 4:1 pitch, which is the most standard, typical binding size you will come across and 5:1 pitch, which provides a cleaner finish due to tighter coils but has a more limited range of book thicknesses it is possible to bind.
These coils are also available in a longer 36" length perfect for cutting down to your desired length. However, due to the specialized nature of these pitch of coils, the shorter 12" length is a better deal cost-wise.
Call 800-399-2564 or email to discuss ordering colors not listed here! Gold, silver, teal, orange, brown, burgundy, yellow, and other custom colors may be available upon request. Large diameter sizes for blue, clear, forest green, navy blue, and red may also be available upon special request.
Coil Length: 12" long
Please anticipate a 2-week delivery time on all 3:1 coil orders.
