Advantages

The plastic material resists bending and keeps document spines tidy, while the 51 mm diameter accommodates thick documents without compressing pages.

How to use

Open the comb on the comb-binding machine by operating the machine’s comb opener, align the punched document pages onto the machine’s pins, and close the comb over the ringed spine to secure the pages. For manual machines, position the comb over the pins and snap it closed according to the machine instructions. Verify the page order and adjust the comb position to ensure even distribution and a lay-flat opening. Pages can be removed or added later by reopening the comb on the machine.

Usage recommendations

Choose the 51 mm comb when binding documents near the indicated maximum sheet capacity to avoid tight binding; leave a small margin for covers and heavy paper. Store the combs flat and away from direct heat to prevent deformation, and match comb diameter to document thickness for optimal lay-flat performance.
