Essentially mini SLCD's, these amazing little units live for shallow thin splitters and odd shaped flares. Unlike other sliders on the market, Tech Nuts don't weld, making them easy to both place and clean. Flexible protected cable allows Tech Nuts to be placed horizontally and prevents walking. They are color-coded for quick identification on route and come in 6 size configurations. An essential piece of hardware for the competent climber looking to fill the holes in his rack.
