W&H has been using a powertwist style belt on our molders since May of 1998. The powertwist belt, reduces machine noise, eliminates belt slippage, absorbs vibration and outlast conventional belts.
54-404: 45" belt is used on our stands manufactured July 2010 to this date.
If you are purchasing a 54-402 Stand this belt will be needed.
54-406: 47" belt is used on our older style stands prior to July 2010.
