The dust foot assembly for Desktops with routers is only for DT2418 tools with a router (not a spindle). It consists of two parts an upper and lower. The upper section clamps to the lower bearing housing of the spindle or to the router ring if a router.  The lower section is then attached to the upper with magnets making it easy to remove for bit changes.

Be sure to select complete assembly (003433), shroud/upper only (15228), or skirting/lower only (15226) above. 

For Desktop and Desktop MAX tools see the Dust Foot Assembly for Desktop Tools with Spindle.
