Best Retrozone in 2026

The Retrozone RZ3-1M 24 vac 2 wire spring return damper motors are designed as drop in replacements for Honeywell's M847D series motors on popular ZD and ARD dampers, including M847D1004, M847D1012, and other M847D series motors.

These motors also replace most Honeywell 2 wire normally open, power to close spring return motors, as well as many other brands

These motors are also replacements for the Hansen 135-6 motor, as well as other brands with the same footprint.

★【Clean Installation】- How to clean up your cluttered battery terminals? Our terminal strips greatly simplified and neatened up your install. The pressure washer style terminal accepts a bare wire and the jumpers allow signals or power to be distributed neatly. This way you can easily disconnect a wiring branch without taking down the entire system.

★【Heavy Duty】- Our terminal/barrier strips are well made sturdy and with quality and robust screws. You can crank down on these for a firm bite. These allowed you to connect each power wire very cleanly to each source (ground, battery, and ignition on). Great for compact wiring jobs.

★【Protect Cover】- Our dual row screw terminal strips that also include a clear cover to protect accidental touching of the terminal. It will be more safer when the terminals are protected by snap-in plastic "lids". Be careful when mounting these covers.

Fourteen connections with 2 x 5/16" stainless steel studs and 12 x #8 stainless steel screws. Comes with 4 x 8AWG 5/16”, 4 x 10AWG 5/16”and 24 x #8 insulated ring terminals

Reinforced Polycarbonate cover attaches with nylon nuts to protect against accidental short circuits
