These are the installed starting prices we work from, and which one applies depends on the gate. Sliding: a Benincà BULL from $3,050 for a residential rack-driven operator, $3,950 for the 1,000 lb BULL 1024 SE and $4,950 for the heaviest commercial BULL; LiftMaster from $5,300 for an RSL12UL, $6,950 for an SL3000UL and up to $9,250 for an industrial slider. Swing: a LiftMaster LA400UL package at $3,950 and an LA500UL at $4,450, each for a single leaf, or $5,350 and $7,150 for a double gate with the control board, primary arm and secondary arm, with commercial swing operators from $6,950 to $9,150. LiftMaster barrier arms from $7,450, arm included. Every one of those includes the monitored photo eye UL 325 requires. CAME is the lower cost line: swing from $2,950 for a single leaf AXI, slide from $3,050 with a BXV, and a GARD LT4 barrier from $4,950, with a pair of photo eyes included on the swing and slide prices. Quoted separately after the site visit: the second operator for a double gate on the other swing models, running power out to the gate, trenching, repairing the gate itself, loop detectors, access control and permits, because those depend on the property and not on the motor.
