Vertical Lift Dimension Selection Tables

Instructions:

  • Using Table #1, determine the over-all height requirement (Dimension “E”) for your application based on the desired clear opening height.
  • Using Table #2, determine the panel thickness and other dimensions for your application based on the desired clear opening width.
