The job, start to finish

Where it started

This iron double gate between two stone pillars was already built and hung. It just was not automatic.

What we did

We welded operator mounting brackets to the gate frame, mounted LiftMaster swing operators, and mounted the control box beside the pillar. On a return visit we fitted an electric lock where the two leaves meet.

  • Operator mounting brackets welded to the gate frame
  • Electric lock fitted where the leaves meet
  • Operators and control box mounted at the stone pillar

How it turned out

Both leaves now open on their operators, and an electric lock holds them shut.

Good to know

Questions we get about jobs like this

Can you add an opener to my existing gate, or do I need a new gate?

Usually yes, you can keep your gate. It needs to be structurally sound, swing or slide freely by hand, and travel reasonably level. An operator cannot fix a sagging gate or seized hinges. If the gate needs work first, we do that fabrication in-house rather than sending you to a second contractor. We will tell you honestly if the gate itself is past saving.

How do you size a gate operator?

Four things drive it: gate weight, gate length, how many times a day it cycles, and the site itself, meaning slope, wind load on solid panels, and travel distance. A light residential swing gate needs a very different machine than a 30-foot commercial slider that opens every few minutes. Operators also carry UL 325 usage classes from residential through industrial, and installing the wrong class is the fastest way to burn one out. We measure and count cycles first, then recommend a model.

What safety devices does an automatic gate legally need?

UL 325 requires monitored entrapment protection in every zone where the gate could trap someone, typically photo eyes across the opening and contact edges on the gate itself. Since 2016, operators must actively monitor those devices; if a sensor fails or is unplugged, the gate stops running in automatic mode. Warning signs and screening to keep hands out of a sliding gate's mesh are part of the standard too. If your gate moves with no sensors on it, get that corrected before anything else.
