How to use

Align the punched or bound pages and document cover, then insert the spine clamp strip along the spine so that the clamp engages the holes or the binding edge. Press the strip firmly along the spine to secure the pages. For best results ensure holes are aligned and pages are stacked evenly before inserting the strip. Removal is done by pulling the strip off the spine, allowing pages to be separated or reassembled as required.

Use the 12 mm strip for documents of moderate thickness; for thicker or thinner sets select a more appropriate strip width. Store strips flat and away from direct sunlight to maintain shape and colour. Pair with compatible punched covers for a professional-looking finish.
