Review on Pack of 50 Black Cable Tie Base Saddle Type Mount Wire Holder with Self-Locking, 6 Inch & 0.145 Inch Cable Zip Ties, #8 x 0.6 Inch Black Deep Thread Pan Head Screws by Andy Hearshman

I used them to route RJ-45 across a large room. I didn't want the cord just lying on the floor. They are easy to install and I used cabinet screws to fasten them into the studs every 16 inches. They fit perfectly and don't interfere with the cable. I installed it on the wall instead of the baseboard so the cord wouldn't interfere with moving the furniture to the baseboard. Not very pretty to look at as they are a bit bulky but they are very secure.
