The clear screw-on housing can be hard to tighten or loosen if a good seal is made with the O-ring inside. That's why people recommend a wrench for the filter housing. The bracket is for attaching the whole house filter to your bench to hold it tightly when removing or installing the clear filter housing with a wrench or your hands. Without the bracket, it is hard to hold the filter and remove the bottom housing with a wrench.
