Hello Corada,
Thank you ETA and Dan for pointing me to this How-to video on measuring handrail extensions. This video clearly demonstrates the length and dimension of what is expected but often misunderstood by contractors and architects. I just shared this with a contractor to reinforce what is expected for the minimum length handrail extension. Once again, Corada has been a very beneficial resource. Great job Corada!
