Whitfield ULTRAGRATE II, W/BASEPLATE KIT_12151264
This is the manufacturer's retrofit upgrade for the original larger Ultragrate 6 7/8" version. Adapter base plate and upgraded smaller grate are for use with the older style Whitfield Advantage II, II-T & III.
***A superior aftermarket alternative to this kit (order both parts) uses laser cut stainless steel for superior durability.
The combination adaptor plate and burn grate convert the 14 bar, 6-7/8" wide Ultragrate, which enables use of the smaller 5 1/4" grate 12051263. The more narrow grate improves your burn rates and makes further adjustments to your control panel less likely. The factory abandoned the 14 bar 6 7/8" original burn grate and replaced with the smaller 5 1/4" 10 bar "Ultragrate" by adding a base plate to fill in the larger opening.
