Slimfold Products Limited Lifetime Warranty

Slimfold® Products Division warrants to the purchaser that its products, when utilized for interior door use, will be free from defects in materials and workmanship for the life of the product.

Slimfold® Products manufactured with galvanized steel are additionally warranted against rusting for a period of one (1) year from the date of purchase, provided the finish has not been cut or abraded through the metal. Galvanized steel should be used where air has a high salt content or in locations with high humidity; see specifications.

This warranty is applicable only when the products covered by it have been installed in accordance with the recommended written installation instructions of Slimfold® Products Division and with established building practices, have been accorded treatment which is considered good practice in the building industry regarding storage and maintenance, and have been subjected only to normal use. Because Slimfold® Products Division cannot control the manner in which its products are handled after leaving its premises, this warranty does not apply to the finish or other damage occurring during shipment.

There are no warranties, express or implied, which extend beyond the description on the face hereof, including the implied warranty of merchantability and the implied warranty of fitness for a particular purpose.

Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply in some cases.

In the event the original consumer purchaser of any Slimfold® product believes that the door or any parts thereof covered by this warranty is defective, a letter outlining the alleged defect should be sent postage prepaid to the following address:

Slimfold® Products
Division of the Dunbarton Corporation

The purchase price of the part will be refunded and does not include labor, installation costs, finishing costs, or indirect or consequential damages of any nature. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

This warranty bestows certain legal rights, and you may also have other rights which vary from state to state.
