Standard is a format label
The B031 retailer description calls the product a standard roll. That is a useful format label, but it does not identify your holder’s permitted outer diameter, core diameter, width or clearance. We have not tested a holder or measured a delivered roll.
Read the exact dispenser limits
Before a bulk purchase, read your dispenser’s exact model requirements and request the supplied roll specification. Keep the holder’s maximum dimensions separate from the roll’s nominal dimensions. A photograph showing a familiar cardboard core does not establish clearance inside a closed dispenser.
Substitution can change dimensions
The seller’s substitution condition makes this especially important. An alternate48-roll,420-sheet case may preserve the count while changing physical details. If exact fit is required, request the brand and model that will actually ship rather than relying only on B031 in the page heading.
Unknown is not a fit verdict
The source finder returns published fields and marks unsupported equipment questions unknown. It does not approve fit from a diameter alone. If the model, supplied brand or current technical sheet is missing, pause the compatibility decision while retaining the valid count and budget information.
Sources and limits
Current maker bodies unreadable and PDF routes failed. Retailer bodies read; exact supplied brand, current certification and independent material/content review pending.
