Ratchet wrenches should be used to build your robot, not built into them. This simple add-on slice allows you to make any VersaPlanetary gearbox drive in only one direction.

Unlike a ratcheting wrench, we’ve designed the VersaPlanetary Ratchet Slice to be as easy to release as possible. Just take the load off the ratchet, press the button, and the VersaPlanetary will spin in both directions again. Release the button, and the VersaPlanetary goes back to ratcheting.

Inside, the ratchet itself is symmetrical. This means you can decide which direction the VersaPlanetary spins just by flipping the pawl. No need to completely disassemble your entire VersaPlanetary to change directions!

Note: This product does NOT need to be greased.
