Fastening Climbing Grips to a Block Wall

For instructions in text form, please see below:

    Items you'll need:
  • Hand-held drill (Hammer Drill if possible)
  • Screw-on climbing holds
  • 5/32" Masonry drill bit
  • Masonry Screws
  • Phillips head drill bit
Fastening climbing holds to concrete walls with masonry screws is a great way to save time and money on your climbing wall. It's also a great idea if you don't want to build a wood climbing wall. If you have bolt-on holds you'll need to use Drop in Anchors.

Step One:
Grab your drill and 5/32" masonry bit and pick the place you want your climbing hold to be. Drill all the way through the front of the block wall, or about 2 inches into solid concrete. If you are installing multiple holds, you should repeat this step at each place you want to install a climbing hold before moving on.

Step Two:
Next you'll need a screw and a climbing hold. Put the screw through one of the holes in the hold to make sure it sticks out the back far enough.

Select proper screws

Step Three:
Fasten the climbing hold to the wall with your phillips drill bit.

Make sure you rotate the hold to the position you want before tightening the screw all the way. Fasten each climbing hold you want to install with one screw before moving to the next step.

Drill first hole Step Four:
When each hold is fastened with one screw, you'll need to drill the holes for the remaining anchor points.

Select proper screws Step Five:
Now fasten the remaining screws. They don't need to be super-tight, just enough the keep the holds from moving. When all the screws are in, your wall is ready for climbing!

  • Screw-on climbing holds can be purchased with Masonry screws and a 5/32" drill bit.
    If you choose this option, the only other thing you'll need is a hand-held drill!

    What is the difference between
    Bolt-on holds and Screw-on holds?

    Bolt-on holds generally have one anchor point. They require 3/8" socket-head bolts and the installation of 3/8" T-nuts in the back of the wall. Once the T-nuts are installed, fastening and removing the holds is extremely easy. All you need is a 5/16 hex key/wrench.

    Screw-on holds always have at least 2 anchor points. The pre-cast holes in each hold are 1/4" in diameter. We generally use 2" weather resistant deck screws to fasten them to the wall. You will need a power drill with a philips head bit to install and remove these holds.

    Screw on climbing holds are great if you want something secure that doesn't require much maintainence.

    Why are there two holes in the Green Bolt-on Hold?
    The second hole is a 1/4" hole just like the ones in the screw-on holds. For most indoor climbing walls, you don't need to use the set screw hole. Moisture and temperature changes will cause the wood on outdoor climbing walls to expand and contract which can loosen bolts. If you fasten a deck screw through this hole it will keep the hold from spinning when a climber grabs it, even if the bolt is a little loose.
