Transom Operator Applications & Specifications: Our transom operator is patterned after a 1920’s original unit and is designed to work on bottom-hinged windows up to 18” x 24”.
We’ve seen these operators used on bottom-hinged windows up to 20” x 30” and on small top-hinged windows up to 12” x 24”. As long as the window can be easily opened and closed using a thumb and forefinger grasp on one side of the frame, this operator can usually be used. Please be sure that you have adequate headroom above the window for installation, 9’ min. ceiling height is usually required.
Due to the 100’s of different window sizes and styles used over the years, there is no way for us to determine the suitability of the this operator for use on windows outside of the parameters listed above. (Please don’t call or E-mail just to ask if we think it will work on your window, all we’ll do is tell you to order one to see if it works!) !
We do not publish a specifications sheet other than the picture shown above; the mounting positions for the wall and frame hardware used on one window might not work on another due to differences in size, weight, and friction. Usually some experimentation is needed to find the optimal hardware mounting points.
We can supply longer wall rods and “Z” rods for higher or larger windows, we cannot design the needed parts, we can only manufacture these custom parts to your specification. We cannot guarantee that they will work on your window!
Stock Transom operators are covered under our 60-day “satisfaction guaranteed” policy. As long as you don’t cut or alter the rods, we’ll refund your purchase price if it doesn’t work out.
