Single Product Information

What it is: 

• It can be  used as a hand-hole to access valves, gauges, thread-o-lets and weld-o-lets that would be otherwise covered up with the Insulation, or it can be used as view hole to observe thermometers, gauges and so on within the Insulation Snake Products. 
• It is a plastic two-piece flange that has 4 screws to secure to each other. 
• This two piece insert allows easy access to what is under neath the insulation, such as a pressure safety relief valve on a propane  tank.
