ATR Service Precision NAB Hub Hold-Downs
An ATR Service Classic — Reengineered and Back in Production
After several years of unavailability, ATR Service is pleased to reintroduce its highly regarded Precision NAB Hub Hold-Downs, now completely reengineered and returned to full production.
Originally developed and manufactured by ATR Service, these premium accessories became popular among professional recording studios and discerning analog tape enthusiasts for their precision construction and secure reel mounting.
Unlike conventional NAB reel adapters, ATR Service hold-downs are engineered to provide accurate reel positioning, secure mechanical engagement, and exceptional stability during tape transport operation.

A Legacy of Precision
The original ATR Service NAB Hub Hold-Downs earned a following among professional analog tape users before manufacturing was discontinued.
Recognizing their continuing value, ATR Service undertook a complete reengineering effort to restore production while preserving the distinctive mechanical features of the original design, including its later-generation three-plunger centering system.
The result is a premium, precision-engineered accessory designed for those who demand the highest standards of mechanical performance from their analog tape equipment.
