Folder binding accessory ESSELTE 21781 — black, max capacity 60 sheets

ESSELTE 21781 folder binding accessory in black is a slide binding strip designed to bind and secure up to 60 sheets (approximately 6 mm capacity). The compact accessory converts loose pages into a single bound set without punching, enabling simple finishing of reports, manuals, invoices or handouts for office, school or home use. It is compatible with slide binding workflows where quick presentation and low cost are priorities.

Advantages

The slide binding strip provides immediate book-like presentation by sliding over the paper edge and clamping sheets together. Its tool-free operation removes the need for punching or additional binding equipment. The slim black finish keeps documents neat and unobtrusive while offering a reliable hold for moderate capacity documents. This option is economical and suitable for frequent small-batch binding.

Suitable for

• Binding short reports and handouts
• Student assignments and school materials
• Invoices, statements and simple office documents
• Creating manuals or user guides with low to moderate page counts

Key specifications

• Colour: black
• Maximum capacity: approx. 60 sheets (around 6 mm)
• Type: slide binding strip for edge binding
• Paper handling: no punching required, sheets inserted directly

How to use

Align the loose pages so their edges are even, then slide the binding strip over the aligned edge until it clasps the stack. Ensure the pages are fully pushed into the strip to achieve an even clamp. No special tools or machines are required; the process is manual and suitable for quick assembly of small document sets.

Usage recommendations

For best results, square the pages by tapping them on a flat surface before inserting into the slide strip. Limit each bound set to the specified capacity to maintain a secure hold and avoid overfilling. Store unused strips flat and protected from bending to preserve their clamping performance.
