The Riser Plates are approximately 5 inches square and 3/4 of an inch thick. They are stackable with the help of the Universal Plate and add not only height, but add a lot of strength.
Our Riser Plates are a great add on. These don't stack by themselves but will add strength and height when added to the Universal Plates.
This is truly the muscle of all the plates. These plates are made of a strong plastic, but will flex, the flex is needed to avoid cracking or breaking. When stacked the ribbing works together to provide the support needed.
