Hello, We have put together a hardware order but have one part that we can not seem to identify. Please see photos of drum roller attached that we need to ID.
We would be looking to order Thirty (30) of these. These would be used with Swisco series 152 coil balances for 9 lb. sash.
The Series 152 is a possibility, as it is 1/2" thick. However I can't really be 100% sure based on the cover alone. Can you show me the pivot shoe? If I can see the pivot shoe, I can confirm beyond any shadow of a doubt what spring would work best.
The top section of parts you selected look good. If the sash is 9 pounds, you could go with one 5 pound spring on each side. I think that will work. As for the coil spring cover, we carry the newer style that seems to have less resistance; our 15-150S. The coil spring is cradle above the curve base behind the cover.
