Milo, Thank you for your question on the Delta Porter 3-Piece Bath Hardware Set with Towel Ring, Toilet Paper Holder and 24" Towel Bar in SpotShield Brushed Nickel. As the manufacturer, we do not recommend cutting the towel bar as it has not been tested to be cut. Best, Customer Care Team
5-3/4” inside face to inside face; 6-1/2” outside face to outside face (about 3/8” thick ring).
My experience with Delta Porter Collection is that it does not come in a 30" towel bar. The longest I was able to get was the 24".
Throw away the anchors supplied. They always pull out of the wall or wiggle. Install the support bracket with metal toggle bolts approx 2" long. This will secure the support brackets. If you can secure directly to a stud it is even better. I used this method on a hollow door as well as sheetrock and can pull on them without any wiggle. The hardware should snap on tightly after you have secured the support bracket properly.
Just pull them off (up) from the top. They hook in kind of like a hanging picture so you can just pull up to take them off to paint
Yes, it is great
No, made in China.
24" comes in the set, but you can buy the 18" seperately
