Used for saw-cut installations where a 3/16” groove is cut into the concrete or asphalt and the wire is stuffed and sealed (using
loop sealent) into the surface. Custom polyethylene outer jacket protects a micro-dusted nylon coated inner jacketed 16AWG stranded
wire. The saw-cut loop has a built in backer-rod securely fitting a 3/16” saw-cut groove eliminating the need to apply backer-rod to
hold the loop to the bottom of the saw-cut groove and requires 30-40% less loop sealant to seal the groove. The entire loop including
the lead-in fits within a 3/16” saw-cut groove preventing wasted time spent double saw-cutting or doubling blades to cut the home run
The only preformed saw-cut loop with a true installation kit designed to ensure a perfectly size cut every time. See more about the
Each loop will need its own loop detector unless you have two loops that are performing the exact same functionality and meet all the requirements found in this document, you then can use only a single loop detector.
Proper loop installation information
Use this formula to calculate how far from the gate the loops should be place so that by the time a car reaches the gate, the gate will be completely open:
Exit Loop formula: x*(y*1.46)=z
x = time for gate to open in seconds.
y = Desired MPH to reach gate.
z = how far from gate.
FYI - 1.46 converts miles per hour to feet per second. We also recommend adding in 10 to 20 feet so the gate is fully open at comfortable distance from the
For placement of a safety loop before and after the gate use the formula below. A safety loop is designed to stop the motion of the gate before the car reaches
the gate. The distance below should give an ample amount of time for the gate to stop before hitting a vehicle:
Safety Formula: 4 feet before a closed gate and after an opened gate.
When installing the loop wire, it can be placed in an irregular shape, and you will want at least 2 feet of space between the edge of the driveway and the safety loop. The short side of the loop will determine the height of the vehicle it will be able to detect. A safety or exit loop with a short side of 4 feet, will detect cars that are at least 2.7 feet tall. To calculate this height, multiply the short side of the loop by 2/3rds.
