– Primary or Supplemental Sash Weights –
for use in restoring double-hung windows

Windowweights.com is your single source for window weights, sash weights, and old-fashioned pulley weights in cast iron. Custom weights are also available in steel where different diameter weights are required.

We manufacture two types of window weights.

The ‘Original’ Stackable Window Weights

Type 1: a 1 1/2 lb. primary or supplemental window weight.

Type 2: a 2 lb. primary or supplemental window weight.

These first two stackable weights are designed to fit over all existing window weights and sash weights, as well as to stack upon any combination of our 1 1/2 lb. and 2 lb. window weights. These are typically used when adding thermal glass.

By using combinations of the 2 lb. window weights and a 1 1/2 lb. window weight, virtually any weight can be achieved. For example: a 7 lb. window weight would be made using a combination of two 2 lb. and two 1 1/2 lb. window weights.

• Supplement existing weights – to use when installing insulated glass.
• Designed to fit over virtually all weights formerly produced.
• Stackable to make any weight required.
• Tens of thousands sold to countless satisfied customers.
• Cylindrical shape prevents unwanted snagging and hang ups which are typical of the opposing square design.

Our New Adjustable/Breakable Window Weights

Our second variety of window weights are usually used as a primary weight. These have the old-fashioned design of window weight top for attaching a sash or a chain.

Type 3: This window weight has the old-fashioned window weight top and comes as an 8 lb. window weight and may easily be field adjusted from 4 lb. to 8 lb. in increments of 1 lb. by snapping off the required 1 lb. segments.

Type 4: Type 4 window weights are an 8 lb. supplemental weight which easily attaches to our Type 3 window weights by simply screwing the threaded top of a Type 4 weight into the bottom of a Type 3 window weight. Type 4 window weights may be field adjusted by snapping off any excess weight to create a supplemental window weight anywhere from 1 lb. to 8 lb. thereby making the 8 lbs. of a Type 3 window weight infinitely adjustable to any weight required in excess of 8 lbs.

NOTE: Type 4 window weights are NOT intended for use without Type 3 window weights.

• Replace lost weights – “I heard it rattle, down the wall, all the way to the basement.”
• AIC 886 easily modifies anywhere from four to eight pounds.
• AIC 887 easily modifies anywhere from one to eight pounds.
• The secondary AIC 887 weight easily screws onto the primary 886 weight.
• Easily attaches to chain or rope.
• Cylindrical shape prevents unwanted snagging and hang ups which are typical of the opposing square design.
