How to Use the Drawings

  • Each download is a one-page Karver technical plan: front and side views with the key dimensions in millimetres, plus a 3D view.
  • The title block gives the model, the Karver part number, the working load, the weight and the material. On these plans the title blocks repeat the text in French and English.
  • Check the maximum line diameter (marked "max" on the side view) against the line you plan to run before you order.
  • Plans are drawn to the scale shown in the title block. Use the printed dimensions, not a measurement taken off the screen.
