UL MARK

The Certification Mark of UL on the product is the only method provided by UL to identify products manufactured under its Certification and Follow-Up Service. The Certification Mark for these products includes the UL symbol, the words "CERTIFIED" and "SAFETY," the geographic identifier(s), and a file number.

Additional Certification Markings

Products may be marked with any applicable qualifications to the product hourly rating.


The UL symbol, the letter "F," and any qualifications to the product hourly rating are cast or stamped on the exposed surface if the entire Certification Mark is not visible after installation of the product.


Products additionally investigated to ANSI/UL 10C may be so noted on the product.

Alternate UL Mark

The Listing Mark of UL on the product is the only method provided by UL to identify products manufactured under its Listing and Follow-Up Service. The Listing Mark for these products includes the UL symbol (as illustrated in the Introduction of this Directory) together with the word "LISTED," a control number, the product name "Manual Flush Bolt" or "Manual Surface Bolt," and any qualifications to the product hourly rating. In addition, the UL symbol, the letter "F," and any qualifications to the product hourly rating are cast or stamped on the exposed surface if the whole Listing Mark is not visible after installation of the product.

UL had previously authorized the use of the letter "f" to denote products that comply with the positive-pressure-test requirements from those that complied only with the neutral-pressure test in ANSI/UL 10B. All products in this category now comply with the positive-pressure requirements of ANSI/UL 10C. The use of the small letter "f" is no longer required for products in this category. Some manufacturers re-tooled their dies and may be marking their products with both an uppercase "F" and lowercase "f."

Products additionally investigated to ANSI/UL 10C may be so noted on the UL Listing Mark.
