Renz Binding Wire 3:1, 9.5mm, 3/8", White – Box of 100

The 3:1 pitch indicates the spacing of the wire loops, which supports binding up to about 400 sheets in a single document. This makes it suitable for thicker reports and manuals.

The product is sold as a box of 100 wires. Each wire has a 9.5 mm diameter and comes in white for a clean, professional appearance.

It's designed for thicker documents, such as manuals, large reports, and manuals, up to roughly 400 sheets, depending on paper weight and binding machine settings.

Use it with a compatible 3:1 wire binding machine. Open the binding spine, insert the spine through the document stack, align the pages, close the spine, and trim any excess wire if needed. For best results, follow your machine’s user manual and ensure the wire is loaded correctly for 3:1 binding.

This wire is designed for systems that use a 3:1 binding spine. If your machine supports 3:1 wire spines, you can bind large documents, otherwise you’ll want to use a wire with a compatible pitch that matches your machine.

Handle with care to avoid sharp edges. Wear gloves if needed to prevent cuts, and store wires in a dry, cool place away from moisture to prevent corrosion or rusting.

Store the wires in a dry, cool environment away from moisture and direct sunlight. Keep the box closed when not in use to prevent dust accumulation and to maintain wire integrity.

Ideal for binding large reports, manuals, training materials, year-end summaries, and other thick documents where a strong, professional binding is required.

They offer a higher capacity binding (up to about 400 sheets) with a durable 9.5 mm wire diameter and a clean white appearance, making them better suited for large, professional documents and longer-term use.
