End Caps & Feet
Many power racks and cages have their base frames sitting on the floor. When a power rack is sitting on metal on concrete or worse carpet, it can easily slide around. If this is how your gym is set up you will know exactly what I am talking about.
Once you have used a squat rack that has rubber feet they just feel that little more solid. The other benefit is that the rubber does compress a little, which is perfect if your floor is a little uneven. After assembling a lot of gyms in a lot of different places, most gym floors are uneven!
Although these rubber feet are branded, you can use them on any piece of gym equipment based on the outside diameter of your base tubing. If you have recently moved your gym and lost a foot, you don't have to remove all the feet and go back to sitting bare on the floor. Replace the missing foot and feel stable again!

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.
Any other important reason why gym owners need to replace end caps is for safety. The end caps also cover the steel edges. As the gym manufacturer is going to use these end caps to blank off ends, they won't round off any sharp edges as the end cap will cover these.
End caps come in a variety of shapes and sizes. You choose which one will fit based on both the outside and internal diameter of the tube you are looking to plug.
Normally you will be able to base your decision off the outside diameter, as the internal diameter which will be determined by the steel thickness, won't vary much between machines.
However if your tubing is either very thick or very thin, it is probably best to check. In these cases you can get the caps to fit. They might just be a bit tight or loose.
