Stackable Lead Weights

SRS offers stackable lead weights in 10 pound increments for use in sash with a minimum thickness of 1-34″. The stackable feature allows you to easily optimize a mix of lead and iron sash weights to match sash weight with minimal waste.
When selecting weights, 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 in the weight pocket. Oversize weights can impede sash movement and cause the window to malfunction. The 1-34″ square cross section allows for the greatest weight in a given weight pocket, crucial when dealing with heavy, wide or insulated units.
To calculate the length of our weight stack, a 10lb weight 8.54″ (total length, plus pyramidal top .74″). Only add the .74” top once, as additional tops nest into the weight immediately above.
Case pricing assures our customers the very best price of $3.40lb. Cases are in stock for immediate shipment.
