block and tackle balance for use in hung windows

AmesburyTruth launched Pinnacle, a block and tackle balance for use in hung windows. The universal mounting clip allows for installation into existing specifications, while still fitting in most standard window profiles. The product yields a reliable lockup directly into the balance that minimizes zing-ups and offers a stronger pivot interlock system, leading to increased window performance ratings, more forgiving manufacturing tolerances, and highly efficient window assembly, say officials.
