Quick delivery and installation are possible, with smaller control windows, with El Dorado’s stock of standard sized telescopic view frames. Telescoping control window frames are supplied fully lead lined with an integral all purpose telescoping section to accommodate all types of wall construction. Frames are designed to fit walls ranging from 4 inches to 6 1/4 inches thick. The standard 2 inch face x 1/2 inch deep face return is aesthetically pleasing and is constructed of 16 gauge steel with corners fully welded and ground smooth.

Frames are ordered from El Dorado using actual glass size. To calculate the rough opening necessary from the actual glass size, add 1 1/2” to the width and 1 1/2” to the height of the glass. To calculate the overall frame dimensions from the actual glass size, add 4 1/4” to the width and 4 1/4” to the height of the glass.
