Avery - AVE77711 Keep the safety data sheets for your facility secure with UltraDuty SDS Poly Binder with a 36" long chain. Designed to withstand constant use and the harshest of conditions, the industrial-grade, polypropylene binder is built with a durable, flexible plastic that can endure damage from water, abrasion and chemicals such as heptane, isopropyl alcohol cleaner, sodium hydroxide and more. Front and back covers are also wider than those of traditional binders to cover divider tabs and sheet protectors. Detachable chain ensures that your safety data sheets stay hooked into your SDS binder holder or rack so that they all stay in one place. Metal chain features clasps that hook into a reinforced hole in the binder spine so that the binder rings and locking mechanism do not get damaged over time. The 1-1/2" slanted binder rings can hold 375 sheets of standard, 8-1/2" x 11" paper.
