Product Identity

The Swingline 4000104 binding spines are black plastic comb elements designed for 19-hole pre-punched paper and covers. They work with any comb-style binding machine to create neatly bound documents and presentations for office or educational use. Each pack contains 100 spines with a 150-sheet capacity. The durable plastic construction allows finished documents to lay flat when opened.

Installation Notes

Using these spines is straightforward: open the comb on your binding machine, thread the 19-hole sheets onto the fingers, and close the comb to secure the document. The most common issue occurs when the sheet count exceeds the 150-sheet limit, which prevents the comb from closing fully or causes pages to tear. Ensure all holes align properly before closing to avoid misbound edges.

Compatibility Check

Before ordering, verify that your binding machine uses standard plastic comb spines and that your paper stock is pre-punched with the 19-hole pattern. These spines are not suitable for wire-binding, coil-binding or thermal-binding equipment. Confirm the 150-sheet capacity matches your typical document thickness; thicker projects will require a larger comb size not included in this pack.

Questions about this item

How can I confirm the 3/4 in black plastic spines are working correctly after binding my first document?

After binding, the 150-sheet capacity spines should let every page lay completely flat and turn smoothly without snagging on the 19-hole comb pattern.

The pack contains 100 spines — do I need to buy 19-hole pre-punched paper and covers separately?

Yes, the 100 black plastic spines work with any comb-style binding machine, but 19-hole pre-punched paper and covers are sold separately.

My projects vary in thickness — when should I choose the 3/4 in 150-sheet black plastic spines over other sizes?

Choose the 3/4 in black plastic spines whenever a document reaches up to 150 sheets; thinner documents need smaller spines, thicker ones need larger diameters.
