Steam Radiator Vents

TWO Maid-O-Mist # 4 (slowest)

TWO Maid-O-Mist # D (fastest)

FOUR Heat-Timer VariValve Quick Vents.

The Maid-O-Mist vents cost new about $11 in NJ.  The VariValve Vents cost about $23. 

These are the wrong vents for me.   Too slow or too fast.  They were used for a few weeks last season 2011-2012. 

Asking $70 including shipping.
