SPECIFICATION

system shall be used where necessary for securing CTS water supply stub outs

when penetrating a wall. Bracket shall be corrosion resistant with twisted ends
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
brackets and simultaneously compresses on tube to prevent stub out movement.
LockBlocks shall be compatible with copper, CPVC, or PEX tube. Optional flame-
rated blocks comply to UL94-VO standards.
