Frequently Asked Questions

What is Trine?

Trine is a manufacturer of electric strikes and door-entry hardware. It is best known for electric strikes and entry hardware.

What products does Trine make?

Trine's product range includes electric strikes and door-entry and intercom release hardware.

Are Trine products fail-safe or fail-secure?

Trine electrified hardware is offered in both modes. Fail-safe unlocks when power is lost, which suits openings that need free egress or fire release; fail-secure stays locked on power loss, which suits perimeter security. The right choice depends on the opening's egress and security needs and the local fire code.

Where is Trine hardware typically used?

Trine hardware is specified for access control and apartment or building entry.

Is Trine hardware commercial grade and code compliant?

Yes. Trine manufactures to commercial standards and tests its products to the applicable ANSI/BHMA A156.31 for electric strikes and A156.23 for electromagnetic locks. For most commercial and institutional openings, specify Grade 1 where the product line offers it, and confirm any fire-rating or ADA listings the opening requires.

Will Trine hardware work with my existing access control system?

Yes. Trine devices run on standard low-voltage power (typically 12 or 24 VDC) and integrate with most access control panels, readers, and credentials. Match the voltage, current draw, and fail-safe or fail-secure mode to your system and power supply when specifying.

Does National Lock Supply sell genuine Trine products?

Yes. National Lock Supply is a stocking distributor of genuine Trine electric strikes and entry hardware, with competitive pricing, real-time availability, and expert support to help you specify the right part. Browse the full Trine line or contact us for project quotes and cross-references.
