All the hardware to make it whatever you need it to be. The center section will release with some heat and a new wider or narrower one can be made to custom build this Tripod Block to whatever size you are desiring. Or perhaps it's the perfect size as is. Not wide enough for Kodak 2D 8X10. Is it for 6.5X8.5 Kodak? Century? Eastman Improved? I just don't know. No returns. The pictures tell you exactly what to expect. The rest is up to you.
