Andersen 531 Narroline Sash Balancer

Mechanism failed at 18 year point. Needed to match exact window with balancer. Lots of good encouragement on the YouTube and from Andersons website for DIY. Hardest part was removing side vinyl/plastic panels without cracking or scraping casement. Patience and persistence paid off.

Installation was a breeze. You take the two window sashes out and the top cover for the balancers. The current balancer was just stapled into place so I had to pry it out. The new one went in with the screws provided. Now I dont have to use an old plastic bottle to hold the window open anymore.

Perfect fit!

The perfect fit

ordered two and only received one. contacted sender and they sent me the missing item. other then that, all is good

perfect fit shipped fast

Did what I expected it to do

Perfect fit

Almost as easy to install as the videos show. Taller windows are easier to do as you have more room to bend the plastic jamb covers. best to do in warm weather when plastic is more pliable. take your time, dont drop the sash. An extra person to hold the sash during the procedure might help. works great.

These fit was perfect with a little retro work that was spelled out in the directions
