Protectors for Letter-Size Pages

These Business Source 74449 sheet protectors hold 11-inch documents without punching. The top-load design keeps inserts secure during frequent handling. Each box contains 100 clear sleeves for classroom or office filing.

Polypropylene Resists Sticking Under Daily Use

The 3.3 mil material prevents printed ink from lifting or adhering to the sleeve surface. A reinforced binding edge withstands repeated turning in binders. Die-cut corners let heavyweight pages move freely without tearing the protector.

Replaces Thinner or Non-Reinforced Sleeves

Standard light-gauge protectors often split at the holes or cause pages to stick. This upgrade is worth it when documents are handled daily or stored long-term in ring binders. Oversized binders and indexes are not included.

The three-hole punched sides fit standard ring binders; oversized binders are sold separately.

Will letter-size documents load correctly into the 11-inch top-loading openings?
