The Frost King AC42H Air Conditioner Weatherseal is a high-performance insulating strip designed to optimize the efficiency of window-mounted air conditioning units. Constructed from highly compressible open-cell polyurethane foam, this weatherseal effectively fills gaps between the sash and window unit, as well as between the sash and glass. It serves as a critical barrier against air leaks, dust, and insects while simultaneously dampening vibrations and reducing operational noise. Ideal for both summer cooling and winter heat retention, this 42-inch strip is easy to install and can be cut to size for a custom fit.

Polyfoam wedges between sash and window unit as well as sash and glass for better weather seal. Keeps out bugs too. Sold per each. 24 each per case.

Help your window air conditioner cool more efficiently in the summer and help prevent heat loss in the winter. Made of highly compressible open cell polyurethane foam.

General Ledger Coding

General Ledger Coding is a value added service provided for you at no additional cost.

General Ledger Coding makes accounting easier by providing you with a calculated total of purchases based on your General Ledger Codes.

In addition to traditional General Ledger Summary provided at time of invoice, we can also provide quotes and order acknowledgements with General Ledger Coding as well. We also give you the ability to change a GL Code for one or all items for renovation projects that may utilize a single GL Code. We can also code any of our "extended inventory" items with your General Ledger Code at the time of quote, order confirmation and invoicing as well. We can code our item numbers directly to your GL Codes should our item categories not align directly with your GL Code Categories.

Please contact us if you wish to implement our General Ledger Coding feature.

Any and all prices are subject to change without notice. We will always bill you at current prices prevailing at the time of shipment (excluding backorders). Availability of product can change at any time. We receive products daily and the availability may not always reflect what is in stock.
