Mrs. Putnam was a cranky old school teacher who never let her students get the upper hand. So we named this base after her – it's tough enough to stand up to the naughtiest school kids! The 1 1/2" round, 16-gauge steel tube, welded top plate and adjustable glides ensure stability and durability. Putnam is highly customizable for different table shapes, and it is available with skirting, modesty panels, and electrical components.
