This Prime-Line H 3959 is a universal folding crank handle that fits most casement operator crank spindles. It is diecast construction with a coppertone finish. The universal spline system fits most casement operators. It is easy to install. The folding design is often used to replace the normal crank handle to avoiding interference with window blinds.

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

  • These operator tee handles are used on casement, awning, jalousie, and louver window operators
  • Folding arm is constructed from diecast zinc metal to reduce projection distance and interference with window coverings
  • Universal fit with set screw and plastic inserts which are 11/32, 5/16, 3/8, 9/32 inches all with 12 ridges and a 3/8 inch with 11 ridges
  • Align the adapter with the set screw on the handle and pass the screw through the hole and set directly on metal spindle shaft to hold in place
  • Ensure your operator has been thoroughly cleaned and lubricated and the ridges are not worn for optimal performance, a tight fit is best
  • Note- Please compare the line art drawing and compare with the spindle you have before purchasing (not Universal)
