Aluminum construction diffuser posts intended to be replacements for ones that have snapped off. These posts are threaded, and require the user to create an appropriately sized hole, and use a #4-40 tap, along with an epoxy for sealing and retention purposes. Standard flat matte black anodized finish. 

These posts are used on a variety of devices such as the PEQ2/ PEQ15/ PEQ16/ LA5 and CNVD series of thermal devices.
