Red, blue or black?

Thanks for the response Paul. I'll order a couple blue tips and add some dust caps to see how i like them.

Hi again Paul, just a quick followup on red vs blue tip sash balances. For 23lb triple glazed 28" sashes the blue tip balances work just as well as the red tip ones, maybe even better. And the optional dustcaps should prolong their life, considering the typical black soot on the windowsills. A few comments on your installation video, its not necessary to remove the sash for balance replacement. I was able to disconnect the balance and remove it with the tiltout window at its lowest 90° position. Also figured the correct tension by pushing the spiral up fully into the tube with a fingertip then overhooking the bottom rollpin with the special tool and pulling it down to reengage the glide. Tilt the window back into position, perfect balance tension. Just placed my order for 20 more, plus dustcaps. These parts saved me thousands in window replacement costs! Best regards.
