SKU: RW Category:


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 $1.60/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!

"Proscraper Vacuum Scraper with Tungsten Carbide Blade The ProScraper was recommended to me when I was making slow progress removing 5 layers of old paint on my window frames.  It made the job so much easier and faster.  The shape of the handle was the right fit for my arthritic hands and allowed me to work longer sessions.  It is by far the best scraper I have ever used. I did have trouble changing the blades, but that was due to my arthritic hands and not having the proper screw driver.  Mr. Smith had me send the scraper back to him to check it.  He found the proper screw driver (Torx T10), loosened the screws, and sent both the scraper and the new screw driver back to me at no charge!  This is customer service that goes above and beyond the norm in this day and age.  I highly recommend both the ProScraper and SRS.
