Thank you for making EZ-PLUG #1 in the roofing industry for the past 10 years!Etunk Solutions is the original inventor and developer of the EZ-Plug. Our product contains No Metal which means no condensation build-up or heat retention day after day that could compromise the warranty of asphalt shingled roofs. Another quality of the EZ-PLUG is that it always flexes back to its original shape when stepped on. Metal copycat products could leave a divot under the shingles which again, over time, could potentially compromise the shingle warranty.
Etunk Solutions/EZ-PLUG will always give you the best product available, 100% made In USA, 100% FREE shipping, and 100% satisfaction guaranteed.
