Description
SRS offers square, cast iron stackable sash weights in 1, 3 and 5-pound increments for use in sash with a minimum thickness of 1-3/4″. The stackable feature allows you to easily optimize the weights to match sash weight with minimal waste.
The 1-3/4″ square cross section allows for the greatest weight in a given weight pocket (a crucial consideration when dealing with heavy, wide or insulated units.)
When selecting weights remember; the weight cross section should never exceed the thickness of your sash. Following this rule will ensure that the weights will have adequate clearance and will not collide with one another. This condition is unacceptable and can cause the window to not function.
If you need to determine the length of any given set of stackable weights you only need to add the 1” pyramidal top once, as all of the other tops nest into the weight immediately above.
Lengths: See technical drawing at left.
Case pricing assures our customers the very best price and all sizes are kept in stock for immediate shipment.

We were hired to fix a number of double hung windows which weren’t operating because someone installed heavy plate glass. The original 12 lb weights were no longer doing the job and we estimated that 18 lbs of weight per side were now required. We chose SRS square stackable weights due to the limited space. A stack of 3 – 5 lb and 3 – 1lb weights gave us the 18 lbs we guessed were needed. In fact, that was just a bit too much weight, so in the end we removed one of the 1 lb weights on each side and easily achieved “finger tip” operation!

These weights are great to work with and come in multiple sizes to accommodate whatever loading you need. Highly recommend SRS and these sash weights.
