i have the 860 heated bottle bracket and used my 10 lbs bottle on it, now im trying to sell the bracket as i dont have a nitrous system anymore and a potential buyer was curious as to weather or not a 20lbs bottle worked with it.

 

I think the bottles are just longer, not wider....i may be wrong

 

A 10# bottle is approx 21 L x 7" diameter. A 15# bottle is the same diameter, but 27" L. long. A 20# bottle is 27.5" long x 8" diameter. Will your bracket adjust form 7" to 8"?

 

the 860 heaters are designed for 10-15# bottles...they use an extruded aluminum base to fit the diameter of those bottles
