Precision 9mm Triangle Utility Keys

Each key is precision-formed from corrosion-resistant zinc alloy, with an external dimension of ~57 x 62 mm and a uniform 9 x 9 x 9 mm triangular insert. Sold as a matched pair. Designed for compatibility with triangle-locked enclosures across energy, water, and communications infrastructure — including meter boxes, distribution cabinets, elevator service doors, and secure postal units. Manual measurement variance: ±1–3 cm. Slight visual differences may appear across devices — rely on tactile and dimensional verification against your lock for final confirmation of fit.
