2" Vertical Peg Board Pipes

If you can pegboard easily, try these out and start your new project.
Even though they are obviously two different pieces of different materials put together, they are completely solid with no wiggling or weakness

-Anytime you use a grip like this (like doing pullups on hanging ropes, or hanging a towel from a pullup bar) you are at an extreme mechanical disadvantage, and it requires incredible grip, wrist, and forearm strength (in addition to arm, shoulder, back, and core strength). So, I consider these the most challenging grip progression (currently) offered at Atomik (outside of thicker versions of these, obviously).
-If you are a beginner or strapped for cash, don't bother buying these right now. Buy the regular pegs and thicker versions of them, as well as the ball pegs. Then when you get strong enough, come back and pick these up...and feel like a beginner all over again (and smile because you love the challenge!)

-As other reviewers have stated, these act like lever-arms, and the lower you grab them, the more they are going to want to come out of the receiver. Grabbing them higher will help to mitigate this, and grabbing them so that the peg comes between the index and middle fingers produces the least "pull-out force", as long as it is comfortable to do so (bigger hands will find it easier).

These are nice to use. They have a great texture and construction.
These are also nice for training lock offs.

CAUTION- These grips can slip out when your using them. We have had people get hit in the face when trying these grips. I recommend you use the 15 degree peg receivers to be the most safe with these.

I own several of the peg board pipes (2” and 3” horizontal pipes, 3.5” peg bombs) and can say that the vertical pipes feel the most challenging to me. They have more of a tendency to want to slip out of the receiver, requiring more stabilization and core strength. The orientation of the handle is also more challenging for grip strength. Great product, going to take a loooong while to master these.
