Did you know that the diameter shape of most plastic binding combs is round or circular, however there are some larger sizes that are oval shaped? Every couple of months we get the question asking if the larger sizes come in the round configuration.
For stability and ease of opening when laid flat, the binding combs that measure 1-1/4″ up to 2″ in diameter are oval shaped. Comb diameters of 1/4″ up to 1-1/8″ are created in the round format. The oval shape allows larger booklets with many pages to have ample clearance when turning through the sheets so that the facing edges/corners inside the combs will not scrape together, get caught on each other or bend. Additionally, the oval diameters feature locking tabs at both ends of the comb for added stability. Without those locking tabs, it’s possible that the combined weight of the sheets could force the comb teeth open and un-threading of your pages. In a related post we answered a question about the security offered by these locking tabs: Do The Locking Tabs On ‘Sure-Lox’ Plastic Binding Combs Offer Any Security?
