Technical Documentation


The ICC-ES Evaluation Report demonstrates to the installer and code official that our LOK fasteners comply with the most current building codes. This report also provides the engineer with critical values needed to design safe installations. Reports from ICC-ES are the most recognized reports used by code officials across the U.S. This document can be shared with code officials, engineers, architects and specifiers who may have questions regarding proper use or code compliance of LOK fasteners.

Technical Evaluation Reports (TERs)

TERs document code compliance through task specific testing of our LOK fasteners.  Relying on the most recognized standards (such as ASTM), test reports that comply with IBC Section 104.11.1 are developed for use by building officials and specifiers to approve critical LOK applications.  The following TERs summarize our products’ code compliance. To receive engineer stamped TERs by state, please visit the DrJ website.
