How do I determine my door's hand and adjust a CAL-ROYAL SC Series lock?

[GiaRose]

Determining your door's hand and adjusting a mortise lock like the CAL-ROYAL SC Series is essential for proper function and security. Here's how, based on the CAL-ROYAL SC8480 Heavy Duty Mortise Lock Instruction Manual:

1. Change Latchbolt Handing:

   • If the latchbolt's hand doesn't match your door, remove the fixing screw and pull the latchbolt from the lock case.
   • Rotate the latchbolt unit so the bevel matches your door's hand.
   • Reinsert the latchbolt and secure it.

2. Set Outside Hand of Lock Case:

   • Find the two set screws at the HUB's bottom, one on each side.
   • Remove the set screw on the secured side (outside/keyside) and leave the interior-facing one.
   • Ensure the lock's hub sits squarely in the lock body. Either arrow 1 or 2 on either side should point to the set screw.
   • If a set screw is removed by accident:
     • Push the spring plate aside.
     • Hold the hub using the spindle, rotating slightly until the spring plate is clear.
     • Reinsert and secure the set screw.

Following these steps ensures your CAL-ROYAL SC Series lock operates smoothly and securely.
