MILGUARD SH

Thanks for posting. Please confirm that the metal channel, not including the end attachments, is 27 inches long. If so, please see our S380-27 or S385-27. The only difference between these two Series is the 'depth' of the bottom nylon shoe. With the Series 380 the depth of this nylon shoe is 1 inch, whereas with the Series 385 it is 1-3/32 inches. Compare with your own and see what is best.

Once you know what balance to pick, you must choose a stamp option. Your stamp of 26 4 conforms to our stamp option of 2640, for a window sash that weighs somewhere between 19 through 26 lbs.
