Certaintieed window

Thanks for posting. See our Certainteed 15-192 as well as the S170-407 7 pound spring. This seems to match what you have. Take a look and let me know if you have further questions. 

Sorry, I should have mentioned--the 15-156 and 15-157 are sold separately. Note that if your old cover and drum are undamaged, you could reuse them. Let me know if you have further questions! 

Ah, I'm sorry for not noticing that before. It appears that you have an older version of this pivot shoe. For whatever reason, the manufacturer updated the design of this shoe so that it had alignment lugs on the front face, presumably to work in their newer windows. The bad news is that the older version isn't made anymore at all; they only sell this newer model.

The good news is that our 15-192 can still work, but it does require cutting or shaving those alignment lugs down. That will give the shoe clearance to fit in the channel. I've done it myself and find that it works well.

Just note that any product altered in this way cannot be returned for a refund. You can see more information regarding our return policy here.

I personally use a utility knife to cut them off and shave it flat. Just make sure if you do that to wear a pair of work gloves, just in case. I can't tell you how many times I've nicked my thumb doing work like that, so better safe than sorry.
