Can items such as the hanging apparatus for mini-blinds and window and door coverings be attached to Gorell products without affecting the warranty on the products?
In general, you can attach these types of items to the vinyl frames of Gorell products as long as they don’t interfere with the operation of the products, such as drainage of water to the outside. Be certain to select only fasteners (screws, adhesives, etc.) that are appropriate for the weight and properties of the vinyl. Note also that nothing should ever be attached to the sill area of a Gorell window or door. Depending on the situation, it is possible to void part or all of the product warranty by making modifications.
