HatchLatch®

HatchLatch® Elevator Door Restrictor

When elevator safety is non-negotiable, trust the solution that’s set the industry standard for decades. HatchLatch from ADAMS is engineered to keep elevator cab doors securely shut and locked between landing zones, helping prevent unauthorized entry and reducing the risk of accidents during stalls or breakdowns. With a history of continuous innovation, it delivers peace of mind for both passengers and professionals.

The HatchLatch Legacy

Since its debut in 1995, HatchLatch has evolved through four models–from A1 to A4. Each version delivers new levels of safety, reliability, and ease of use.

Today’s HatchLatch meets and exceeds the A17.1 Code for door restrictors and has held CSA approval since its introduction. It includes everything you need to protect up to a five-story rise, with installation and maintenance made simple through intuitive diagnostics and streamlined design.
