Small climbing hold volumes like this add big variety to steep walls in an inexpensive way. They are versatile and low-profile, making them an excellent choice for a home wall. It's common to not be able to have hard crimps and other small holds on steep walls, but when you add a volume like this, they offer less aggressive angles where you can attach a foothold or a crimp. The four areas to attach holds is 4", so expect all small holds to fit and only some medium holds.
