Each RW 2 2-pound stackable round sash weight is 1-3/8” diameter by 7-1/8” long with a ½” diameter hole running through the center for threading the sash cord or chain. The conical shape at the top is made to fit the corresponding “socket’ of the weight above. By stacking multiple RW 2 weights you can quickly achieve any 2-pound increment. By using RW 2’s in conjunction with our AOW weights any weight can be achieved to balance typical residential sash.

Our RW 1 is a 1-pound stackable round sash weight and measures 1-3/8” diameter by 4-1/4” long with a ½” diameter hole.

Case pricing assures our customers the very best price of $1.97/lb and all sizes are kept in stock for immediate shipment. RW 2 weights are offered in 6-piece cases and RW 1 in 10-piece cases.

    1. Kate Dermody – Bagala Window Works

      These weights are great for adding a couple of pounds to get the perfect counterweight in a pinch if you don’t have the right vintage weight in the van. These weights are nice and skinny so they fit in the smallest of weight pockets – coming in at 1 3/8″ diameter. It’s definitely worth it to have a box of these as back up on-site!

    "I've ordered a number of sash locks from different retailers recently and I would rate your SL 01 as A+. I had a "rattley" window that wasn't closing snug after I replaced the broken weight ropes. When I installed the SL 01, the first time I locked it, I heard a 'thunk' and the sashes set tight and plumb into the frame. I was impressed. R.J. O'Brien"
