How to use

Open the clasp by lifting the metal plate and sliding the pins or hooks apart as required by the fastener type, place the stack of papers aligned to the holes or pin positions, then close the metal plate to clamp the sheets securely. For best results, align paper edges before securing and avoid overstuffing beyond the 35 mm clasp width. Regularly check the fastener for wear and ensure the polypropylene parts are free from cracks to maintain reliable performance.

Usage recommendations

Use the fastener with standard A4 or similarly sized paper and keep the clasp within its 35 mm capacity to prevent deformation. Store folders with fastened documents upright in a dry environment to minimize stress on the metal and polypropylene parts. If frequent opening is required, inspect moving parts periodically and replace the fastener if you notice significant wear.
