Window component identification and defect description please

[Joe Funderburk, CMI]

What do you call the mechanism at the sides of the window for modern, vinyl (or wood) windows that attaches to the bottom of the sash? How do you describe the defect when the mechanism isn't attached? It sometimes keeps the sash from staying raised, and definitely affects the tilt function because the lower sash tilts and may fall out of the frame when you try to tilt it.

1st photo shows a disconnected mechanism. 2nd shows one correctly attached.

Thanks.

good question....

try something like this

The xxxx window has disconnected or broken hardware along the frame edge(s) that prevent proper operation. This affects both the use of and the safety of the window.

Thanks. For some reason, Kevin Costner kept coming to my mind saying, "Engage the mechanism". (For the Love of the Game).

When I worked for The Home Depot, customers would bring them in for replacement on their American Craftsman vinyl windows. The name of the replacement part was a "sash balance". That is all I've ever heard them referred to.

Adjust Tilt Window Spiral Balance


If your tilt windows require adjustment, such as sash dropping or pulling up, or if the spiral rod is disengaged, adjustment is simple:

1. Tilt sash downward to expose balance shoe. Using diagram 1, disengage rod from shoe. Do not disconnect rod from tensioning tool.
   
   
   2. Rotate rod slightly to the right.
   3. At the same time, pull rod downward.
   4. Slip rod away from the pivot lock shoe.
   
   
2. If sash is dropping, add tension by rotating rod clockwise. Do not exceed more than two full turns at a time, doing both sides equally. Reconnect rod, repeat process if needed.
   
3. If sash is pulling up, less tension is required. do both sides equally; rotate rod counter-clockwise one turn. Reconnect rod; repeat process if needed.
   
4. If rod is disconnected from shoe then follow diagram 2, for position of rod before connecting rod and balance. Apply tension to both sides equally, not exceeding four turns at a time.

Michael is correct, it is the balance system for the operation of tilt, single and double hung windows.
Sometimes the Manufacturers will mess up and the balance systems will allow the top sashes of double hung windows to creep down.
This means that the balance was improperly sized for the weight of the window sash and when one is broke or disconnected, the operation of the window sash will not operate adequately and in need of repair.

Thanks everyone. I had googled it earlier but didn't find anything useful.
