a Rubber Seal for a drum that holds 3 pounds of rocks.
Measure. Around 4-1/16 inches across. At the rim, there is a height of 3/16 inches.
Does not come with a metal support disk or bolt.
Sold as a set of three seals.
Rock 3 pound rock tumbler rubber seals from Harbor Freight / Northern and Sears come with this type of seal.
These aren’t as thick as the original and only last for a few weeks at most. When the thin rubber is hit by the rocks, it breaks. The lid’s fastening makes the rubber split. Wasn’t worth it.
