There are maybe 3 different manufacturers for those types of push-lock pull knobs (or more), all with a different center offset. It would be best to post a picture. Rockler, a woodworking site has one type, the type shown at Fisheries is a Sugutsune, who has a "Lamp" brand. I had a totally different type on a Northstar yacht that was supplied from a company that made aircraft interior fittings. They all worked similarly, but were different enough not to work with the hole sizes or offsets.
OEM is Sugatsune / Lamp. as Rick G said. My replacements from Fisheries Supply were correct. Send a pic to Sugatsune if you're unsure support@sugatsune.com
