What Major products does Anderson Lock carry?

A100KA MMC2 KEE-BLOK — for use with knob locks
A200KA MMC2 KEE-BLOK — for use with lever locks
AG1A Latch Protector — Aluminum finish
AG1D Latch Protector — Duranodic finish
These items fall under the Specialty Lock category and are ideal for reinforcing entry security and protecting hardware from tampering.
What are KEE-BLOK key blocking locks?
Major KEE-BLOK locks are designed to block unauthorized key access to knob or lever locks. They fit over the keyway and prevent operation of the cylinder, providing temporary key control during maintenance or restricted access periods.
What are latch protectors used for?
Latch protectors reinforce door frames and prevent tampering or prying at the latch area. Major’s AG1A and AG1D models provide extra protection for outswinging doors in commercial buildings, improving overall entryway security.
Are Major latch protectors easy to install?
Yes. Major Manufacturing designs its latch protectors with locksmiths in mind. They’re simple to install, typically using standard fasteners, and can be applied to most metal or wood doors.
What finishes are available?
We currently offer Aluminum (AG1A) and Duranodic (AG1D) finishes—both durable, corrosion-resistant coatings designed for long-term use in demanding environments.
Can I order KEE-BLOK locks for both knob and lever applications?
Yes. The A100KA model fits knob locks, while the A200KA model is made for lever locks. Both options provide the same level of tamper resistance and quality.
