The Plymouth Rock has been designed as a 360 degree hold. That means it will offer you some version of a hold no matter which way you rotate it.
On a vertical wall, the hardest (bottom if you can read the 1620) will feel like a V2 sloper block. On a steep wall, that same sloper will feel about V6. There are also some pinch/crimp combos.
It measures 15 inches wide, 8 inches tall and sticks out from the wall about 4.5 inches.
