Head Mount

ProMax Ultra FT6841C Professional Carbon Fiber Tripod

There are two different sizes of head mounting screws - 1/4-20 and 3/8". Some tripods have only one size, others have a spring-loaded adapter that can be used with either sized mount hole in the head. Most heads also have an adapter in the mount hole. It would be very unusual to find a head and tripod combination that did not work with each other. Read more in the Tripods article in the All About Optics section.
