At United Door & Gate Multi‑Services / United Door & Gate Manufacturing, we have more than 55 years of combined experience installing, servicing and repairing automatic gate operators for commercial, industrial and residential applications. Our team has installed and serviced thousands of gate opener systems across Miami‑Dade, Broward, Palm Beach, Monroe, Collier, Lee, Martin & St. Lucie counties. We draw on our deep roots in the industry – going back to our early days as Rolling Door Parts – to provide reliable, safe and long‑lasting gate operator solutions. Whether you need a new swing gate operator for a gated community or a heavy‑duty slide gate operator for an industrial facility, we can design, install and maintain the right system for your needs.

Gate Operator Installation

We install all major types of automatic gate operators:
‑ Swing Gate Operators: perfect for residential communities, driveways and light commercial properties. We provide single and dual swing gate systems with AC or DC motors, solar options and built‑in battery backups.
‑ Slide Gate Operators: ideal for high‑security and high‑cycle applications such as warehouses, self‑storage facilities and industrial yards. We offer cantilever and track slide gate systems capable of handling heavy gates and continuous operation.
‑ Barrier Arm Operators: used at parking lots, condo entries and parking garages. We install barrier arm operators with quick opening cycles and optional folding arms, LED lighting and card reader integration.
‑ Vertical Lift & Vertical Pivot Gates: vertical lift gates for tight spaces and vertical pivot gates for high‑security sites. These systems raise the gate up and out of the way, making them ideal for snow or debris conditions.

We partner with leading manufacturers to supply the best gate operator equipment:
‑ LiftMaster and Elite
‑ Doorking (DKS)
‑ Viking
‑ HySecurity
‑ FAAC
‑ Nice
‑ Linear
‑ All‑O‑Matic
‑ BFT
‑ Other major brands

Our installations include careful selection of gate hardware, proper mounting and alignment, welding and fabrication of mounting posts and brackets, and integration with access control devices such as keypads, card readers, telephone entry systems, RFID tags and mobile app controls. We handle all electrical connections and ensure UL‑325 compliance for safety.
