The BUSINESS SOURCE BSN16511CT is a carton of five top-load sheet protectors designed to hold standard letter-size documents measuring 11 by 8.5 inches. Constructed from 5 mil polypropylene, these clear sleeves provide a rigid yet flexible barrier that keeps printed pages clean, dry, and legible. The reinforced binding strip along the insertion edge resists tearing during repeated use, and the three-hole punched design allows direct placement into standard three-ring binders. Die-cut corners on the ring side let pages turn freely without catching. These protectors are well-suited for organizing reference materials, job site documents, inspection reports, or any paperwork requiring durable, long-term storage in a binder system.
Intended for office, field, or worksite environments where protecting letter-size documents in binders is a routine need. The top-loading opening keeps pages secure without requiring additional closure hardware. Each protector accommodates a single letter-size sheet without punching the original document. The carton contains five individual sheet protectors. Oversized ring binders and indexes are sold separately and are not included.
Designed as a standard-fit replacement or addition for letter-size three-ring binder systems. Compatible with binders accepting three-hole punched letter-size inserts at 11 by 8.5 inches. Oversized ring binders and indexes are sold separately.
No tools are required for use. Simply open the top-load edge and slide the document in face-up before inserting the protector into the binder rings through the pre-punched holes. Avoid overfilling individual sleeves, as this can stress the binding strip and reduce protector life. Store binders upright to prevent documents from shifting inside the sleeves.
