Great customer service, sturdy, just the right size.

Perfect fit on Rogue SML-2/HR-2 half rack.

Exactly as advertised! Works perfectly for 3” outside 14g square tubing.

Do the job of capping off the opened ended square tube on my boat lift look is good

looks great and fits great

Sturdy caps for 3 tube. Fit my gate posts perfectly.

Fit great

I fell, and ripped my hand wide open because a building contractor found it cheaper not place these cheap plastic pugs. This metal 3 x 3 x 3 tall is the protection between hot water heater. So your car bumper does hit the natural gas line by accident. I gave the other to the neighbors. Safety Check your garage.

Planned to use for capping a 3x3 steel tube that supports a fence gate. However, the cap isnt large enough to gain enough friction to to anything other that sit on top of the tube. Hope I can find some with larger flexible ridges to hold tighter.
