Why are block and tackle balances popular?

Block and tackle balances aren’t the most popular because they’re an amazing piece of technology, they just happen to be one of the best options currently available. As technology advances manufacturers grow and develop new products and window vendors adapt to these changes as well.

Prior to the introduction of block and tackle balance systems, hung windows used weight and cord or spiral balances. Original weight and cord balance systems were big and bulky, taking up more space in the window jambs. Spiral balances gained popularity after WWII, they were smaller than weight and cord balances allowing window vendors to fit windows with more glass surface into the rough openings. Unfortunately, spiral balances weren’t as durable because the steel material is susceptible to rust. Spiral balances are also known to bend and break within its tube encasement.

Block and tackle systems are small, taking up less space in the jamb like spiral balances but are much more durable.
