Find a lock

Architects & Engineers

Since its founding in 1903, CompX has partnered with architects, engineers and designers and has proven to be a valuable resource to these professionals. CompX provides specifications, AIA CE credits and 3D models, in addition to collaborating on project design and planning. With over 100 years of domestic manufacturing experience, CompX is the right partner to help architects and engineers with their projects.


CompX works closely with architects to help specify the appropriate domestically made cabinet lock(s) for projects, from K-12 schools to healthcare facilities, and beyond. In an effort to help educate and to support the continuing education requirement for architects, CompX developed two classes – both fully approved by the AIA – about cabinet locks.

Continuing Education

Two AIA approved Continuing Education courses from CompX:

  • Introduction to mechanical cabinet locks = 1 LU credit (course # AIACES2023-M)
  • Introduction to keyless access control for cabinets and other enclosures = 1 LU/HSW credit (course # AIACES2022)

CompX has dedicated Architectural Specification Reps, available to help with project planning and specs. Contact CompX for help or if your firm would be interested in hosting a Continuing Education course.

CompX provides 3D models: step and igs files that can be dropped into CAD drawings and can help plan placement and fitment for cabinet lock needs. CompX also provides 3D pdfs, which can be viewed prior to downloading CAD files. 

The CompX dedicated engineering department is available to help discuss and plan projects, to help determine the best cabinet lock for the job, and if needed, to help design and develop a new cabinet lock for any unique situation. From idea to implementation to delivery, let the professional CompX engineers help get your project across the finish line.
