This product is a high-capacity institutional bath tissue roll, with "BTMG" likely standing for "Bath Tissue Mega/Jumbo Roll," indicating a significantly larger roll size compared to standard household toilet paper. "PR" could signify "Performance Roll" or "Professional Roll," suggesting a product designed for efficiency and durability in commercial settings. The "Inst'l" (Institutional) designation confirms its intended use in high-traffic public restrooms such as those in offices, schools, healthcare facilities, and hospitality venues.

The "48/150" refers to the packaging and quantity. "48" most certainly means there are 48 rolls per case. The "150" strongly suggests a large measure of the roll's capacity, typically indicating 1500 sheets per roll or potentially 1500 feet in length, which are common for mega or jumbo rolls used in institutional dispensers. These larger rolls are crucial for reducing the frequency of maintenance and refilling, leading to labor cost savings and improved restroom flow.
