Description

Each RW weight is 1-3/8” diameter 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.

Lengths: See technical drawing at left.

Case pricing assures our customers the very best price and all sizes are kept in stock for immediate shipment.

    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!

    "Holy Moly!!! Just got the email about the new (TL 01) Thumb Latches you're making! I'm sure I'm not the only one to send you one of my old ones/ inquire about availability, but you sure make a guy feel heard! This shows once again why I forgo the cheap imitations online for the stuff you make… forward thinking and responsive with your (re)-innovating product offerings. 5 years I've been looking for these. I'll be buying some this week! It's amazing that any company today is as nimble and responsive as you are for your customers. Now that I can get the Thumb Latches I can finally refurb the windows in my 1774 house without thinking I'm only able to do it "half way". I'm going home tonight and will tally up the quantity and finishes and order them tomorrow!Babcock Patent Lock Richard W."
