(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

Great customer service, sturdy, just the right size.

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.

Fit my Soloflex perfectly

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