Keep the safety data sheets for your facility secure with UltraDuty SDS Poly Binder with a 36" long chain. Designed to withstand constant use & the harshest of conditions, the industrial-grade, polypropylene binder is built with a durable, flexible plastic that can endure damage from water, abrasion & chemicals such as heptane, isopropyl alcohol cleaner, sodium hydroxide & more. Front & back covers are also wider than those of traditional binders to cover divider tabs & 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 & 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.
