Black Plastic Bungs/Plugs

When you measure your square tube, you will need the outside dimension to find your cap in my options. Unless the wall of your tube is very thick then please contact us for advise. 
Caps can handle tube thickness from 0.5 to 2-3mm. 
Made from HARD plastic material, they will provide high wear resistant.
