Questions about this item

How often should the lever mechanism on this 4600LN lock be lubricated?

The free-wheeling lever design reduces internal wear; apply light PTFE lubricant to the latch bolt and lever pivot once per year for smooth operation.

What component reaches its cycle limit first on a Grade 1 4000 series lock under constant classroom traffic?

The latch bolt assembly is tested to ANSI/BHMA 156.2 Grade 1 requirements, so it is the first part rated for replacement after heavy use.

Does the lock body heat up or draw extra power when the lever stays locked all day?

This is a fully mechanical cylindrical lock with no electronic parts, so it generates no heat and consumes no power during continuous operation.
