“The header box is constructed beautifully and is solid and durable. I found the unit to be slightly small for the 6” Prospectors Dream, Dream mat sluice box. Not by much, but enough that it bowed the bottom of the sluice causing a 1/4 inch gap at center under the header box. Some side shims should eliminate most or all of this. It is also possible that maybe the sluice box was built a hair wide. I was hoping it would be easily removable whenever I’d want, but it appears I’ll have to silicon it (which will need scraped off each removal) unless I’m lucky enough to find a thin enough foam gasket that may work. Either way I’m happy with the header box and would recommend it.”
