End Caps & Inserts

End caps are used in gym equipment to blank off ends of steel tubing. This is not only done for aesthetics, it also reduces the internals of the tubing to exposure and therefore corrosion. If steel is painted it generally won’t rust – the paint protects it from the elements. As you can’t paint the inside of tubing, if it is exposed to humidity or moisture it will rust. Therefore it is a good idea to replace any missing end caps.
