Set of four 6 inch long leg risers for Leggett & Platt Adjustable bases

Description

For sale are four 6 inch long leg risers for Leggett & Platt Adjustable bases. Condition is "Used". The thread is 30 MM. I have 12 total of these as I have two Twin XL bases that take 6 each so I ordered three boxes of 4 each. This height  made the bed a little short for us so we ordered 9 inch risers. The 6 in ones were installed and then taken out the a week later when we received the 9 inch long ones. These are in perfect condition. I am selling these in groups of 4. A set of 4 sell on amazon for .50 plus .99 shipping. I am offering them for plus calculated shipping costs via USPS ground. A savings of up to .
I am now including offers but you will still will be paying for the shipping charges on top of the offered amount.
7/16 inch caster rollers with grips can be added to make your base moveable. See the last pic that shows a type of caster roller that can be used to allow the base to be moved around.
