A collection of screw on holds created for use mainly on "woodie" walls.
These holds are created from polyurethane plastic and have a very friendly fine grain texture that lends itself to training the muscles more than the skin. Every hold has "pre-drilled" set screw holes that are created in the manufacturing process and contain a metal set screw washer to make your hold stronger. If you want to be real cool you can take some fine grain sand paper to them to create a very comfy hold that is nearly impossible to hang onto. This is probably unnecessary but will get you very strong if you can still hang on... #protip
