Hi.
I purchased 7/16" nylon wheels with pins from you for my older aluminum sliding windows. I removed one of the old wheels and put the new wheel in its place. The wheel fits and the hole for the pin lines up, but the pin is too large for the existing holes. The holes in the aluminum frame are very close to the edge so I'm afraid to drill a larger hole to accommodate the pin.
The pins that came with the wheels are 4mm Outside diameter. Do you have pins 3 or 3 O.D?
Also, I had difficulty removing old wheel so I used a soldering iron to melt it. It was messy- first time I've used one.
Any suggestions?
Thanks so much,
Leslie
