THE PULLMAN SASH BALANCE.
A MORE PERFECT and ECONOMICAL
Balance than Weights and Cords.
Works smoother and easier
than any other device.
No Boxes or Pockets in Frame necessary.
IT IS ADJUSTABLE.
Made entirely of steel. The best coil spring is used, it being encased in a drawn steel drum, and a metallic tape fastened on outside of drum to operate sash.
Is very compact, occupying space required for ordinary sash pulley.
This Balance entirely overcomes the difficulty of friction occasioned by counter weights.
It relieves the entire heft of sash. A 75 to 100 lb. sash works as easily as a very light one. Applied to old windows as readily as to new, without altering frame or sash. Will last a lifetime.
