Get me the UL certificate for mortise lock Yale serie 8800

I’m unable to provide specific documents or certifications such as UL certificates for products, including the Yale series 8800 mortise lock. However, you can typically obtain this information directly from the manufacturer's website or contact their customer support. Ultra-Lock (UL) certification is important for ensuring that the product meets certain safety standards, and this information is usually available in the specifications or safety section of the manufacturer's documentation. Alternatively, you may also want to check with your local distributor or retailer for the specific documentation you need.
