The steel cap fits right over a standard dimension 2x4 post and the MGM Steel Challenge target plates hang perfectly on the hook which is cut from MGM AR-550 steel - same as the target plates, so you won't wear it out.
Steel Challenge Cap w/ target hook only. Target plate, and base sold separately or in complete sets. 2x4 post not included.
This base can be used with MGM Steel Challenge targets or MGM BC-C Zone® target (with 2x4 bracket for use with DLP).
