Keeping Washington secured since 1979
A second-generation, privately held company in Enumclaw, focused on automated gates, access control and perimeter security.
Pioneers in Pacific Northwest gate automation
Our founders saw a need in the Pacific Northwest for automated security gates, access control and perimeter security, and opened Trinity Gate to fill it. For more than 40 years we’ve served industrial, commercial and residential property owners with security and access control built around how their property works.
Today Trinity Gate is a second-generation, privately held company. The family legacy and values remain: the best products and service we can give, for customers across Washington.
Licensed, bonded and insured in Washington: General Contractor TRINIGD042C6 and Electrical Contractor TRINIGD965CP.
