Installation Pro-Tips

1. Templates are Key: Mortising a door requires precision. Use a sharp chisel or a dedicated mortising router bit to ensure the pocket for the lock body is snug.

2. Door Swing: Before installing the strike plate, verify your door's swing. If the latch is facing the wrong way, you can pull and rotate the latch bolt $180^\circ$ without opening the case.

3. Lubrication: To keep the mechanism working smoothly in salt air, apply a small amount of clear silicone grease or Tef-Gel to the internal moving parts before final assembly.

Are you replacing an old Perko lock?

Perko has kept their dimensions consistent for years, so this is often a perfect "drop-in" replacement for older brass or chrome sets. Would you like me to help you verify the mounting hole spacing to ensure it matches your existing door cutouts?
