Hello,
I placed an order and received it promptly but it appears that the plastic part on the lower end of the balancer may not match watch I have. These are S380's. The profile of the part seems nearly identical to mine but the portion that would ride up against the window sash (the plastic ramp portion with two protruding ramps) is 2mm taller on the new part.
I've attached some images comparing old/new and some measurements.
I thought maybe the old part had worn down a bit but other windows I had with less have the same 5mm height for that portion.
I had ordered a set of s380's way back in 2016 and they did fit a window (perhaps they were wrong or I got luck and had enough play in that window for them to work).
I tried to install the two shortest s380's I ordered in my kitchen window but the sash was just about stuck (almost impossible to move up or down, sides wedges in with the new balancers). I was able to get it out so that is when I compared parts more closely.
Please let me know what you think.

Thanks for reaching out to us. Rather than measure the projection of the ramp, can you instead tell me the total depth of that bottom shoe? That's how these are meant to be measured. I just want to be 100% sure that we get you the right hardware. If they end up being 7/8" deep then your balance will have to be custom made with a 15-029 bottom fitting. Once you've confirmed that depth, I'll email you a purchase link and price quote that you can use to place your order. |

Sure, if you're fine with that that then it's totally possible. Not a lot of customers are comfortable drilling out rivets and all that so they tend to just opt for an all new balance, but changing nylon fittings is a quick and effective solution in situations like this. See our 15-029 shoe, 62-005 rivet, and 75-075 rivet tool. You may also find the video below to be helpful. |
