88L Series Caldwell Ultralift Window Balance 88L-37s57W

37-1/2" Caldwell Ultralift Window Balance. 57 lbs window. White Tube. Balance stamped 37-57 lbs Ultralift.

The heavy duty Ultralift is not only an excellent product for counterbalancing windows from 10lbs. to 100 lbs.; it also reduces the manual force required to open and close windows by 50%. Standard balances only provide about 40% of the sash weight while the Ultralift lifts 70% of the sash weight. This makes the Ultralift an excellent product to use in nursing homes, schools and windows that are difficult to access. 

Here are the facts:
• Lifts 70% of sash weight vs. AAMA'S 40% minimum.
• Provides even power across full range of sash travel.
• Usable with both tilt and non-tilt windows.
• Adjustable on site by +/- 2 lbs.
• Fits most C-20 and HC-40 AAMA grade single and double hung windows.
• Fits most large architectural wood windows.
• Combines spiral and extension spring technology.
• Custom made for specific sash weights
