Continuous Hinge 3 Point Latch Enclosures

Continuous Hinge 3 Point Latch Enclosure Applications

Nema Enclosures, a leading manufacturer, specializes in crafting single or double door NEMA 4 and NEMA 4X enclosures for both indoor and outdoor applications, catering to diverse industries such as manufacturing, petrochemical plants, pulp and paper processing, wastewater treatment facilities, and packaging. This design is particularly popular for larger-sized enclosures, including freestanding, floor-mount and double-door wall mount or dual-entry applications.

Our continuous hinge 3 point latch enclosures feature a user-friendly three-point latch locking system with Teflon rollers and a stainless steel rod mechanism. This system ensures effective and simultaneous securing of the top and bottom of the enclosure door when the key is turned, facilitating easy installation and significantly enhancing door-locking security compared to single-point locking enclosures. The 3 point latch mechanism provides a watertight seal, earning the enclosure a rating of up to 4X without the need for tools to unscrew all of the clamps. This superior pad-locking system demonstrates our commitment to delivering high-quality, secure, and water-resistant solutions for diverse industrial applications.

Consideration must be given to the sealing surface size, as an excessively large surface may lead to areas where the gasket is not fully compressed. For enclosures with a maximum width of 42 inches, the 3PT latch mechanism excels, preventing cover bowing and ensuring uniform compression across the sealing flange on all sides to prevent ingress. Underwriters Laboratories has validated this design through rigorous testing, with thousands of enclosures in the field showcasing its reliability.

For customers prioritizing even compression and purge capability, the quarter turn latch or clamp latch style design is recommended, ensuring all latches are engaged to avoid potential cover bowing and reduced compression in specific areas, preventing ingress. At Nema Enclosures, our commitment is to provide secure, reliable, and industry-approved solutions tailored to the diverse needs of our clients.
