LiftMaster MASTDCBB3 24V Mega Sprint Tower Arm, Aluminum Alloy Chassis, Radio Receiver Built-In

For high‑cycle commercial and security applications, the LiftMaster MASTDCBB3 24V Mega Sprint Tower Arm delivers fast, reliable access control where uptime and throughput matter most. This DC‑powered barrier gate operator is designed to handle up to 6,000 cycles per day with a rapid 2.5‑second open/close speed, reducing vehicle wait times in parking garages, toll booths, and secure entry lanes. The T‑6 aircraft‑grade aluminum alloy chassis provides superior strength and corrosion resistance while remaining light enough for one‑person installation, lowering labor costs. Built‑in battery backup ensures the operator and connected DC control devices continue functioning during power outages—helping maintain site security and uninterrupted monitoring. With an integrated radio receiver and auxiliary outlet, the MASTDCBB3 simplifies integration into access control and surveillance systems and reduces additional hardware needs. Backed by LiftMaster quality and a 2‑year limited warranty, this barrier arm operator is ideal for commercial parking, gated communities, and critical infrastructure entrances.
