There are so many fixed key pinches! Let's spice things up and add a roller! This one will truly challenge your key pinch strength, especially if your thumb is your weak point.
Place your fingers on the plate side, and your thumb on the roller side. Thumbs can be straight or bent, but either will surely give you excellent training!
The finger plate is 3" in length and 1.25" in height.
Although the rollers are interchangeable, it is recommended that you don't switch them out as the different diameter rollers have different sitting heights. A larger roller won't fit on a base designed for a smaller roller, and a smaller roller will have too much space below it if put on a base designed for a larger roller.
By default, the finish on the rollers are kept to raw steel to support consistency in competitions and also to allow for natural seasoning.
