Hollow Metal Standards

I recently needed to refer to a copy of HMMA-850, the NAAMM/HMMA standard for fire rated doors and frames.  I was pleasantly surprised to find this standard on-line as a free download.  Upon further digging, I found that almost ALL of the HMMA and SDI publications can be downloaded for free from their websites.  There is a wealth of information there, including free downloadable specifications and ANSI standards.  If you’re an architect or specwriter, you can even request a complimentary bound copy (or CD) of the SDI Fact File which includes all of their publications.  Click the links below to check out the list of standards available for download.

HMMA – Hollow Metal Manufacturers Association, div. of NAAMM

SDI – Steel Door Institute

    Hi Lori, I noticed below as I was going through your writings.

    The SDI link you have (http://www.steeldoor.org/resourceTechData.php) on this page (http://idighardware.com/2009/06/hollow-metal-standards/) has moved to http://www.steeldoor.org/tech_data.htm

    great site.

    Hi Lori,

    I need your help and expertise on this.

    What is the standard jamb depth on an aluminum frame with SNAP ON STOPS.Is it (3-1/2″, 4-1/2″, 4″ OR 2-1/2″)?

    Thanks in advance.

      The most common frame back when I was working with aluminum frames was 4 1/2″ but that may have changed over the years.
