SRS offers cast iron stackable 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 stack of weights you only need to add the 1” pyramidal top once, as all of the other tops nest into the weight immediately above.
Lengths; 1 lb weight: = 1-1/2″ L. (plus pyramidal top); 3 lb = 3-1/4″ L. (plus pyramidal top); 5 lb = 7″ (plus pyramidal top).
Case pricing assures our customers the very best price of $1.60/lb and all sizes are kept in stock for immediate shipment.
