These are reproduction hand formed side guards (part number BS-214-S) for the older model Delta 6 X 48 belt sander.  Each one has been fitted to several different machines to ensure proper fit.  Although there are minor differences, it is difficult to tell my reproduction side guards from the original.  They have received a coat of epoxy primer. Please note that the holes for attaching the Delta badge are not drilled. 

Replacement side guards are no longer available. Finding original side guards is becoming difficult. I think you will be pleased with the appearance and function of these side guards.

On left of last photo, shows original Delta side guard, on right new reproduction side guard.

PLEASE EMAIL IF YOU HAVE ANY QUESTIONS REGARDING SIDE GUARDS.
