I have a 20"x60" panel with a heavy wooden frame. I need to hang it within an existing modern window space from the interior existing sash header. The frame is really nice and well engineered. I dislike clunky eyelet pairs with cable or chain. You have to rely on eyelet threads to hold the piece up, when the frame maker went to a lot of trouble to make strong joinery. How do the cool people hang panels in existing window spaces? Vic explained a solution once where you drill paths from frame top and back for cable to run into and through the wood frame. I've done that before with small frames, but I thought I'd check to see if there are any other good ways or new hardware available.
I've been using Z-bars to hang some very expensive windows. You place one on the wall (sash here) making sure it's level, the other on the frame, and just set it into place. Got it at Home Depot. Comes in various lengths.
Thank you Vic and Mary for the feedback. Z-bar is good stuff. I've used it for mounting a headboard on a bedroom wall. Easy to get correctly level and lots of fastener position options for security. But we won't have a nice vertical surface to mount a z-bar on. Still thinking. Vic's solution is workable. Still have to put some sort of fastener into the existing window top rail.
