Maximum Controls MAX-ULTRA-ARM Residential & Commercial Heav

Overview

The Maximum Controls MAX-ULTRA-ARM is a heavy duty 24-volt DC linear actuator built for residential and light commercial use. Its corrosion-resistant powder coated aluminum housing, stainless steel output shaft, and direct gear drive — with no internal chains, belts, or pulleys — deliver reliable performance across a wide range of gate sizes and weights. The unit operates across an extreme temperature range of -4°F to 165°F (-20°C to +74°C), including during battery backup operation, without requiring a heater.

Key Features

• Continuous duty brushless motor with 24VDC operational voltage
