Description
1" spiral for a specific binding step
Metal spiral in roll 1" (25.4 mm), white, 2:1(code CADU00180) is a white spiral roll. Diameter value 1" / 25.4 mm combined with 2:1 perforation; the supplier indicates the capacity group "191–220 sheets," and the drum contains 4,200 loops.
Roll for non-standard product widths
CADU00180 spiral is not pre-cut into A4 segments. From the white roll, the exact length of a 1" 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 white 1" coil, the perforation step is first aligned, then the entire bundle with covers is measured. The capacity indicated for the code CADU00180 is indicative: the selected element must allow the pages to turn freely and not press on the binding edge.
