This object was made to hold the pot that comes with the one man vacuum pump bleed kits from Amazon.

They all appear to be the same size, just different branding so the pot should fit nicely and with the slots you can visually check to ensure the pots not getting over filled, if it gets over full it can allow brake fluid to get pulled up into the pump, this object is designed to add a bit of stability and to allow you to keep an eye on what your doing without the pot flopping around.

I cannot stress enough that if the pot is unstable on the ground or in the air you are very likely to pull brake fluid into the pump, if this happens it ruins thr seals and renders it useless.
