Are the dimentions 13x3.5 the outside dimensions. What is the opening size. Also I need nickel satin so which one should I order.A. The Hamilton Sinkler MS-302.13 has an interior flap that is 10" wide and 2 3/4" high. The slot will be just a bit smaller than that. The closest to satin nickel will be brushed nickel.
Can this be used vertically?A. The Hamilton Sinkler MS-302.13 can installed vertically. Although it is made to be horizontally installed, where gravity will close it. This may prove to be an issue of irritation.
