Description

Offering this Steel Plug or clean out Threaded Pipe Head and cap in vintage shape. I am assuming that is what these are. The small top measure 2 3/4" across the top and 2 1/4" underneath where the threads are. The thick cap is appx. 1 3/8" thick and is heavy steel with a threaded hole on one side Embossed Keller Eng. Lyndhurst on top. I am really not familiar with what these are used for so any info from someone that knows would be appreciated.
