Difference between pivots shoes 15-152 and 15-129

Question

Hi, In spite of knowing that I needed the 15-129 tilt window pivot shoe, I somehow ended up ordering the 15-152. However, after going over both of them with a caliper, it seems that the only material difference between the two is that the 129 has a metal brake while the 152 has a plastic one. Can you tell me to what extent the 2 products are interchangeable? Thanks, John

Hey there, John. You are correct, the difference between the 15-129 and 15-152 pivot shoes is primarily in the brake pad. Some manufacturers used the metal brake with success, while others the nylon brakes. The metal brake style, used by the 15-129, tends to be more secure in locking the pivot shoe in the track.

I hope this has answered your question, but please feel free to reach out if you wanted to know anything else!
