R-Clamps

R-Clamps are perfect for attaching landscape lighting cable to trees, decks, docks, and other surfaces without damaging the cable.  U-nails, if accidently installed too firmly, can crimp the cable and even cause the wiring to ground-out. 

These R-Clamps are thick, durable, UV resistant plastic, and are 1/2" wide.  Don't be fooled by cheaper quality R-Clamps that will easily break.
