RPV Head Laser Guide 


The Preferred Engineering RPV Head Laser Guide is a UHMW plastic fabrication that houses a battery operated laser. The top of the Guide is designed to snugly fit the Stud Hole in the flange with a stop for proper installation. The lower section of the Guide includes three ball pins to center the Guide properly in the stud hole. Integral lift cables allow for proper retention once head is set, no falling equipment.
