to mount to the surface either a wood or metal stud wall. System shall include
approved hardware for fastening brackets to stud wall. System shall include
slideable, plastic block device to position and secure CTS stub out at any desired
location. Each block shall include two screws for tightening. When screws on
blocks are tightened, compression of blocks prevents lateral movement on
