I use simple eye hooks and small elastic cords to hold my 5 or 10 lb c02 bottle in place. Cost < $5 at Home Depot.

Takes 4 eye hooks that screw directly into the cabinet (inside), 2 on each side of the cylinder and spaced appropriately.
Place the cylinder between the hooks and hook one end of each strap to the eye hook and you are all set. Since diameter of 5 and 10 lb is the same, no change there.....

Pic is worth a thousand words.

Look for the blue bungee cords and the eye hooks around the cylinder........

Hope this helps.

Smart idea. You seem to have a bunch of DIY tips. Keep 'em coming!
