(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

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.

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.

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

Great customer service, sturdy, just the right size.

Fit my Soloflex perfectly

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.

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

Work and fit nicely, finished the look and keeps out the weather and bees and bugs.

Fit great
