Description
3/4" spiral for specific binding steps
Metal spiral in roll 3/4" (19.05 mm), black, 2:1(code CADU00164) is a black roll coil. Diameter value 3/4" / 19.05 mm combined with 2:1 perforation; the supplier indicates the capacity group "136–160 sheets," and the drum contains 8,000 loops.
Roll for non-standard product widths
CADU00164 spiral is not pre-cut into A4 segments. From the black roll, the exact 3/4" length of the element is cut for a specific calendar, notebook, or brochure, so the yield depends on the number of loops used in one product.
What to check before pinching
When choosing a black 3/4" coil, the perforation step is first aligned, then the entire bundle with covers is measured. The capacity indicated for the code CADU00164 is indicative: the selected element must allow the pages to turn freely and not press on the binding edge.
