Mantis set of 10 holds can be used on any wall, but they were designed for setting hard problems 30 to 45-degree terrain. Excellent set for blasting your forearms. They are slightly incut to about the first digit.

This set requires 10 x 1.5" bolts.

View on Your Wall

Depending on your MOBILE device and browser you may have the option to view this hold/set in Augmented Reality (AR) on your wall. Will not work on desktop.

How to view in AR:

  1. If you see the link "View on Your Wall", simply tap the link and wait for 1-4 seconds.  Link not visible?  Your device/browser is not AR capable.
  2. When your camera opens and the 3D model of the hold appears, point your camera at a well lit wall and the hold will be "placed" there.  If your camera does not open, your device/browser is not AR capable.
  3. Once placed, you can move your device around the hold, get close, move out, above, below, place your hand close to it, rotate using two fingers.

I have tested using an iphone 12 pro (ios 17.1) and latest versions of Chrome, Firefox and Safari and they work perfect.


  • Best results seem to be with Chrome, Firefox and Safari.
  • Wall/surface needs to be well lit
  • Seems to help for there to be something else on the wall, like art, light switch, door/window frame close to where you want to place object, needs reference points
  • If hold moves around, then it needs some reference point close by, see point above
  • Brick/textured walls work well
  • Object can be placed on flat surfaces too, but since it is a climbing hold it will be oriented vertically
  • You can rotate the hold with 2 fingers
  • Hopefully soon you will be able to place object on overhanging walls in the correct orientation
  • Not working but you feel it should?  There are so many variables that could prevent it from working, but the code I am using is written by a third party and I have zero control over it.
  • All bolt-on holds/sets require socket head type bolts, except for the Classic Footholds Set which requires countersunk head bolts.
  • All bolts Uncarved Block sells are imperial 3/8" diameter with UNC threads.
  • Unless otherwise stated, t-nuts are not included with holds or sets.
  • Any items shown in pictures other than holds are to show scale and are not included with purchase.
  • More information about hold colors click here.
  • Bolts optionally supplied with holds/sets are suited for 17-20 mm thick climbing walls, if you require longer bolts order these separately.
  • It is cheaper & faster to select random colours.

Super fun.

These holds are so good. They climb very well on 20-30 degree walls and feel great. Texture is good and just deep enough to hold. Make me feel strong!!

Great incut edges for a 45

Tested on a 45 degree wall. Tendon- and skin-friendly incut edges, most with a decent thumb-catch. Typically one pad deep and wide enough for all four fingers. The two biggest holds are very matchable. Enough variability in size and shape to fine-tune difficulty of problems and stay interesting. Great for problems starting at about V3, and for intermediate climbers wanting to train up their finger strength. My favourite hold set so far.

Favourite set so far

These are perfect edges for a 45 wall. They all have a raised, rounded lip on them for they are much easier to hold than they look, and very skin friendly too. They are so good.... we now have 2 sets
