So the description says, and I'll copy and paste it in here. ( Designed for use with 1/4" thru 10" Model 975XL, 975XL2, 375, 375XL and 475 Reduced Pressure Principle Backflow Preventers on horizontal or vertical installations. However this one only works on the 1 inch units. the opening is too small by nearly 1/4 inch. Just wanted to let anyone know that if you are ordering this for a 2 inch Wilkins double check, it won't fit. Most of my double checks are the 975 XL units.
