• 12" x 1.5" base

• 1.75" Width at widest

• 1/4" deep rounded slopey lip.  Do not be deceived!  If the Limiter 3 had a 1/4" lip it would be easier than the Unlimiter, because the lip is based on a 1" diameter rod. The Unlimiter lip is based on a 2" diameter rod. 

• Difficulty: Advanced, In bouldering terms doing 5 pull-ups on these would be around V5.

• This is 11th version of the Limiter i've designed so far. (Limiter 1 in 2016!) It is a slight variation of the Limiter 1 which was rounded on both sides.  The Unlimiter is now flat on the back making it much easier and more versatile.

• Texture:  Fine 200 grit sandstone texture.  It's grippy, but very fine.  

• This product can be fastened to just about any wood surface, including the doorway using #9 Star-Drive Deck Screws. (included)

• If you are familiar with the Limiter 3, these are going to feel quite a bit more challenging.

• Get a pair for the door way, or get the 8 Pack and set up the full 20' obstacle for your gym!
