(Pack of 4) 3 Square Plastic Plugs |10 14 Ga - 3 x 3 Inch (for ID 2.74 to 2.83) | Flexible Ridges n Side Walls | Heavy Duty Impact Resistant 1/4 Thick LDPE Cap - Tubing Plugs

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.

Fit my Soloflex perfectly

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.

Fit great

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

Great customer service, sturdy, just the right size.

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

The caps are of good quality. However wasnt the right fit for my 3x3 fence tube. Tried returning the item. Says free return in the description, but its not. I gave it 3 stars because the quality is good but -2 for not being honest.

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

They work great. Be sure to get the right ones for the ID. Lots of poor reviews from people who either can’t read or can’t measure.
