TEMPORARY (HOPEFULLY) WARNING – eBay’s system is no longer figuring shipping correctly on orders with multiple units. They are aware of the problem but there is no estimate of when it will be fixed. If you are interested in multiple units, please message me and I may be able to do a work around. As soon as I know the issue is fixed, I’ll remove this language. At the moment, the only workaround is to order half of the units from this listing and the other half from my shipping included listing. re: Dow Styrofoam Sill Seal Foam Gasket 5.5″ wide x 50′ long. NEW Rolls 22.9-sq ft NEW, never-used DOW brand Sill Seal Styrofoam Roll Gasket / Insulation. Manufacturer part number 334174. 22.9-sq ft (5.5-inches Wide x 50-feet Long) Individual Pack This product reduces air infiltration and moisture wicking from the concrete foundation wall into the wood sill plate and the gasket strip can also be used around windows, doors and between floors. Easy to unroll and use. I can ship two rolls for nearly the same shipping price that it costs to ship one. If you want a large number, I will have to package them up in pairs (you may get multiple packages) whenever possible and refund some shipping money on the back end as I am unable to properly get eBay’s shipping quantity to figure out shipping charges correctly thus far. If that changes, I’ll edit this text. Need a large quantity? Shoot me a message and I’ll see if I can accommodate. We’ve done our best to show all sides of the item(s). Please review the photographs carefully as they are part of the description. We DO NOT use stock photos for anything. From a non-smoking home. We are not pet-free. If you have any questions please feel free to ask. Where possible, we try to reuse or recycle materials as much as possible when packing & shipping. This not only saves you money, it also helps divert usable materials from going to the landfill at least for a while. RETURNS: Items MUST be returned in the originally described condition. In the case of new and/or sealed items that means only if they are returned in the same new and/or sealed condition. If a problem is found in a single item which is part of a lot, everything in said lot must be returned in original condition. No exceptions. Please keep in mind that Kentucky is one of 27 states that require the collection of the 6% KY sales tax on shipping. That will come up on your total when checking out. Thanks for looking at our offerings and for supporting small sellers.
