The Meter/Pit Insulation Plug is made of strong, durable 1.2# laminated closed cell foam with a 2.5 R-value per inch. Available in 2”, 4” and 6” thickness, all plugs are cut with a slight taper allowing a snug, easy installation.  The taper keeps the plug tight and in place, sealing up any variations in the interior wall of the pipe ensuring the plug is doing the job to insulate. The slight taper reduces plug tipping when being installed and the high visibility handle allows for easy removal.
