The YHM HUB Direct Thread Mount (brand part number YHM-2189-M) converts a HUB-compatible suppressor to a direct-thread mounting system, with a barrel-side thread cut to M13.5x1LH. Yankee Hill Machine machined the mount from 17-4PH heat-treated stainless steel and finished it in Black Oxide, with a standard 1.375-24 HUB thread on the suppressor side and a .45-caliber bore. Installation is simple: remove the existing mount mechanism from the suppressor, thread on the HUB Direct Thread Mount using a 3/4-inch open-end wrench, then thread the whole assembly onto the barrel.
