UniCover Spine - Binding Spine with Tear-Away Covers

The UniCover Spine by Unibind is the replacement product for the SteelBack spines. Each thermal binding spine has a temporary cover what is torn-off after the binding process. UniCover Spines are a perfect way to bind documents quickly. The steel binding spine allows you to bind your documents with a cover page of any type. You can either use your own cover, or one of Unibind's many custom CoverSets, or with no cover at all.

UniCover Spine - Colors

UniBack spines are available with the following spine colors: Aluminum, Azur, Black, Bordo, Dark Blue, Dark Green, Quartz and White. Choose a color that best matches your corporate colors or brightly stands out from the rest. Aluminum, Azur, and Quartz colors have a unique metallic finish, where Black, Bordo, Dark Blue/Green, and white have a more traditional finish.
