Up for Sale is a Single Kidder Barn Door Roller with Patent Dates Apr 30, 1878 and July 3, 1879. Wheel turns freely and iron has no cracks or chips. This roller would have rode on a wood track as it has flat wheel surface and no groove. The roller guide is missing (see photos 9 & 10) which would prevent the door from riding off the track. Hole could be drilled out and replacement guide used. Keene, NH Find! 15 1/2" total length, Wheel is 4 7/8" diameter x 1 1/4"W, mounting footprint is 6 3/4"H x 3 3/4"W
