Hello, Thank you for reaching out to our support with this specific kind of question. We'd be happy to answer this. The tripod thread is standard: 1/4-20, which means ¼", with 20 threads per inch. This is specified by ISO 1222:2010. If this is the normal size tripod one has, then it should work well without any issues. Hope you find this helpful to make your purchasing decision.
