The BUSINESS SOURCE BSN32375 is a double-sided clear polypropylene binder pocket designed to maximize document storage in standard three-ring binders. Each pocket features a slash pocket on both sides, allowing each side to hold up to 20 sheets of letter-size 20 lb paper. The 8.5 by 11 inch profile fits letter-size documents without trimming. Polypropylene construction resists sticking and prevents ink lift, keeping documents protected during regular handling. This pack includes 5 pockets, making it a practical restocking option for office, classroom, or field-use binders.
These binder pockets are suited for residential and commercial office environments, classrooms, and job-site document management where organized, protected sheet storage is needed inside a three-ring binder. The three-hole punched edge fits standard binder spine configurations. Each pocket serves as a dual-capacity sleeve, effectively doubling document capacity compared to a single-pocket sleeve. Typical users include office administrators, educators, and anyone managing reference materials, inspection sheets, or project documents in a ring binder system.
Designed as a standard replacement or addition for letter-size three-ring binders with a standard three-hole punch pattern.
No tools are required for installation. Simply align the three-hole punched edge with the binder rings and snap closed. Avoid overfilling beyond the rated 20-sheet capacity per side to prevent pocket stress and document damage.
