Norton 7570 RH 689 Grade 1 Security Door Closer

Norton 7570 RH 689 Grade 1 Security Closer delivers robust security and reliability for high-traffic environments. Designed as a regular rigid security arm door closer, it features an adjustable size range of 1-6 to accommodate various door configurations. The right-handed model comes equipped with a durable security cover and tamper-resistant Torx screws, ensuring enhanced protection against vandalism and unauthorized tampering. Constructed with a cast aluminum alloy body, this surface-mounted closer projects only 2-3/16" from the door surface, maintaining a sleek profile. It operates effectively in extreme temperatures, from -40°F to high heat, thanks to its specially formulated closer fluid that retains stable viscosity. The Norton 7570 includes adjustable valves for independent sweep and latch speed regulation, along with backcheck cushioning to prevent damage during operation. Each unit is reversible and comes with a handed metal cover securely fastened at four points to deter prying. Ideal for use in prisons, schools, government buildings, and financial institutions, the Norton 7570 is a Grade 1 closer that meets rigorous safety and durability standards, making it a preferred choice for commercial applications where security is paramount.
