Hotel bathroom tilt windows

This is a coil balance system: namely, our 15-177 Pivot Shoe and Series 152 Coil Balances. For new housing for the coil springs, see the 15-145, 15-143 and 15-144. Let me know if you have further questions. 

No, I am afraid the Series 140 is not interchangeable with the 15-177 and Series 152. With rare exceptions such as the Series 140, coil balance systems do not come as entire assemblies; each part is modular, meaning they are sold separately. The good thing about this usually is that it means any undamaged components you don't really need to replace. However, it does mean accounting for more separate items. Apologies for any inconvenience. 

Note too that you'll need to select spring weights for each coil balance. The spring weight indicates the weight each individual coil can support. This is typically denoted by a stamp somewhere on the coil spring, usually near the tongue. If there is none or you are unsure for a given window, please tell me its exact weight. This can be achieved by placing the window sash on a bathroom scale. Give me that exact weight, and I can work out the spring weights you need.
