Just shy of 3" tall and equipped with a 3/8-16 male thread that fits perfectly with your Swift Plate :)
 
Used as a set to raise your plate above a surface, clearing external hard drives and power sources bolted below... or as a solo baby pin to attach something to the top of your cart. Pictured here with the excellent LavaCart deck set based around an RNR R12 Stealth.
 
The possibilities are more than two, but realistically less than "endless".
