The Incredibowl XL Expansion Chamber is half the length of the XXL version at 10 inches ( 25.4 cm.). It is designed for the m420 Steamroller and is manufactured from tough, heat-resistant polycarbonate tubing.

The already impressive m420 will be considerably boosted by the addition of this expansion chamber providing smokers with an incredible hit of smoke.

If you love your m420 then you really must try one of these bad boys with it!
