Our premium sash window pulleys are:

The highest quality forged brass pulleys

While our competitors use stamping or sand-casting to create their pulleys, we take the time to forge our pulleys. Because of our forging process, our high-performance pulleys really stand the test of time.

Independently tested to a breaking strength of 7,000 lbs

We had our pulleys tested by an independent engineering house and the results showed that our pulleys withstand 10 times the stress of our competitors.

Custom machined to any size on our in-house CNC machine

We will custom machine our pulleys at no additional cost to you. With CNC machining, we can engineer each piece to optimal tolerances that will give your pulleys the best performance.

Window pulleys have to work, and keep working long into the future. We are so confident in our premium window pulleys, we back them with a lifetime guarantee.

There are relatively few moving parts in a traditional weight and pulley system. Sash have become increasingly heavy with larger glass sizes and double and even triple glazing and the use of very high quality pulleys has become critical. Failure in a pulley (binding, squealing or even a broken axle) results in an improperly operating window.  In these cases, repair can be very time consuming and expensive, involving the removal of trim, sash, weather-stripping systems, disassembly of the weight and chain from the sash, installation of a proper high quality sash pulley, reassembly and re-painting. Pulleys are “deeply”  built into the construction of and are critical to the smooth operation of a well performing double hung window.  It is essential to use the very best.

These sash pulleys are the finest available in appearance, durability, and function. Model PBB 225 pulleys are designed for sash weights up to 1-3/4″ diameter when used in typical 7/8″ thick jambs typical in residential and smaller buildings. Commercial and institutional buildings may require the larger 2-1/2” sash pulley, click here for more information.  The pulley is carefully designed with a precisely machined faceplate and the radiused ends allow for rapid, simple and accurate mortising with a standard 1-1/8″ diameter router bit. Housing body = 2-7/8″ X 7/8″ X 1-7/8″ deep.
