Hi johnsee,
These handles require only a tubular mortice latch, such as our Product Codes 4065K or 5245K.
However, if you mean the other handles in this style, they are the Smith & Locke Sandsend Fire Rated Long Lever Lock Door Handles Pair Satin / Black Nickel (408HY) and the Smith & Locke Sandsend Fire Rated Long WC Door Handles Pair Satin / Black Nickel (367HY).
Thanks for using Screwfix Q&A. JT
