WORKED PERFECTLY ON MY UNIQUE CREATION!!

WORKED PERFECTLY ON MY UNIQUE CREATION!!
We just got our first Old English Sheepdog without a bobtail. His fuzzy tail is beautiful however, it presentes quite a fire hazard. We needed to keep it from flailing too close our glowing red, ventless propane heater. After much research, I chose this RUTLAND product. I used it to attach three glass strips to narrow aluminum channels that serve as legs. Connections feel solid as a rock and allows the assembly to be handled like one solid piece. Minimal smell, easy to use and sets in a reasonable time. The heat resistance remains to be seen, but it's earned my confidence already. I have no reason to suspect it won't perform precisely as promised. So glad I chose RUTLAND!!FOLLOW UP: here we are at the end of the winter season. Thurston's tail is beautiful and fluffier than ever. Thank you Rutland, for promising the world and delivering!!
