82-005 for a Lanaidor Patio Door?

Thanks for posting. While we have recommended the 82-005 to customers with Lanaidor patio doors in the past, these parts are generic across brands, so there's really no way of saying for sure this is a good match for you without seeing pictures of what you currently have. Ultimately, it's really going to depend on the hole spacing and configuration of your current handle set. The 82-005 has a hole spacing of 4-15/16" and is surface mounted, meaning it doesn't interact with an internal mortise lock. If you're uncertain these are your door's current specifications, let us see pictures of your current handle set.
