This is the Medium-Large version of the HOLSTEX® brand SPUMA "Slotted Post Ultra Mounting Assembly". These are used for creating separation and retention in fold-over KYDEX® knife sheaths and gun holsters, magazine clips, flashlight holders, and a multitude of general gear assemblies where fastening and retention is needed in a medium-large sized material gap. The SPUMA (Medium-Large) by HOLSTEX® includes all of the parts needed to perform the fastener assembly function, including the exclusively designed metal finishing washer, which provides an unparalleled degree of refinement to the finished rig's mounting points.
The difference in the SPUMA (Medium-Large) mounting assembly and over-the-counter parts is that the SPUMA (Medium-Large) was developed exclusively for holster making use, to insure that each part works together with the maximum degree of precision when used with standard KYDEX®, HOLSTEX®, and Boltaron® material thicknesses, and with common holster attachments and rig mounting recesses.
All metal parts of the SPUMA (Medium-Large) assembly are black coated. Each SPUMA M-L assembly comes with its own precision-fit EPDM retention washer (the most precisely fit washer in the industry - no twists, no turns...period!).
