Fill a hole in kegerator

Taking my first step into kegging and found a used keezer online that I'm picking up this weekend. The seller is keeping all the faucets, shanks, etc. So there are 6 holes in the collar ready to go. My problem is I can't afford 6 faucets right now and just want to start with 2. So that leaves me 4 holes in my keezer. How can I temporarily seal these up? I want to add the additional faucets soon, so I need something that will be easy to remove when the time comes.

duct tape....

How concerned with looks are you?

Fill the holes with fiberglass insulation and duct tape in place.

If looks are important then you might try finding a spackle compound that matches in color and use it instead of duct tape.

Not concerned with looks. Just looking for a simple way to keep in the cold air for a few weeks or months before I can purchase the additional faucets. Didn't think of duct tape, that sounds like a no brainer.

if you can't duct it, fuct it!

Use these 7/8 plugs. When I built my kegarator I drilled more hole than I currently need so I did't have to do it in the future and I just filled in the remainder with these.

A 3/4" knockout plug might be about the right size.
