Delta 50-861 filter mounting rings

[Bobby Robbinett]

So I recently acquired a 5hp Delta 50-861 for a great deal and although it came with the huge filters, which are like over 10ft long but it did not come with the rings that mount to the housing which the filters attach onto. Nor did it comes with the filter clamps. The filters are 6 & something inches in diameter and there are 12x filters in all. Do you guys know what the mounting rings are called that the filter bags slip onto? Or where I could source some?

I really hate to have customer filters made that have a 24” diameter because these small ones which there are multiples of would have more surface area and I am guessing that a custom 24” diameter x 12ft or 16ft tall pair of filter bags would cost an arm and a leg. Any suggestions?

In smaller sizes I would call it a bulkhead fitting. I would talk to a sheetmetal shop. A floor flange might work with short nipple. I see fire sprinkler piping with rolled grooves for the clamp joints
