Ateco Large Decorating Coupler
Large Ateco coupler for large pastry tips. This coupler will work with Ateco #800 series tips ending in a 7,8, or 9. If there's any doubt just measure the base of your tip and if it's 1 3/8" diameter this coupler will fit. Also works with large Wilton tips - they just need to be 1 3/8" at the base.
