- Annual maintenance contract: scheduled servicing and support for installed equipment.
- ANPR
- Automatic number plate recognition: a camera system that reads vehicle plates to grant access.
- Bi-folding gate
- A gate whose leaves fold in the middle as they open, saving swing or side space.
- Boom barrier
- A horizontal arm that lifts and lowers to control vehicle entry at a lane.
- Controller
- The control board that receives commands from remotes, keypads or apps and runs the operator and safety devices.
- Dock leveller
- A platform that bridges the gap between a truck bed and the dock floor.
- Dock seal
- A cushion that presses against a docked truck to seal the gap around it.
- Dock shelter
- A frame around a docked truck that reduces dust, rain and air loss.
- Duty cycle
- How often an operator is designed to run, for example how many openings per hour or per day.
- Galvalume
- Steel coated with an aluminium-zinc alloy for corrosion resistance, used in some shutters.
- High-speed door
- A fast-acting door, usually with a flexible curtain, used on busy openings to limit air and dust movement.
- Limit switch
- A device that tells the controller where the gate or door is so it stops at the right open and closed positions.
- Loop detector
- A wire loop in the ground that senses a vehicle above it and keeps a gate or barrier from closing on it.
- Manual release
- A mechanism that disengages the motor so a gate or door can be moved by hand, for example in a power cut.
- Operator

- Sectional door
- An overhead door made of hinged panels that travel on tracks and rest below the ceiling when open.
- Soft start and soft stop
- Gradual acceleration and slowing at the ends of travel that reduces noise and wear.
- Telescopic gate

- Trackless gate
- A gate that moves without a floor track, which keeps the path clear.
