What to check first

  1. Mechanism: straight arm, split/dual arm, dyad or awning. Match the complete linkage.
  2. Hand: use the supplier’s drawing and viewing convention. Clockwise or counterclockwise handle rotation alone is not enough.
  3. Arm or link length: use the exact dimension endpoints shown on the source drawing.
  4. Spline and mounting: compare the handle spindle, screw centers, attachment and arm offset.
