BD Loops Saw-Cut Preformed Vehicle Detection Loop
The BD Loops Saw-Cut Preformed Loop is designed for installations where a 3/16" or larger groove is cut into concrete or asphalt. The loop wire is stuffed into the groove and sealed with loop sealant. This preformed design makes installation faster and more reliable than traditional hand-wrapped loops.
Loops are sold by perimeter size and lead length. Example: An 18 ft perimeter loop can be laid out as 6 ft × 3 ft, 5 ft × 4 ft, or any combination that totals 18 ft.
Key Features & Benefits
- Built-in wing-shaped backer-rod – fits snugly in a 3/16" groove
- Durable polyethylene outer jacket protects 16AWG stranded wire
- Eliminates the need for separate backer-rod installation
- Saves at least 30% on loop sealant compared to traditional methods
- Entire loop + lead-in fits in a single 3/16" saw-cut – no double saw-cutting required
- Directional arrows on wire + red/black lead-in for easy phasing
- Twisted jacketed lead-in prevents coil back and saves installation time

Recommended Minimum Size
- Minimum 3 feet wide for standard vehicles
- Wider (4–6 ft short leg) recommended for taller vehicles or commercial use
Installation Note
Important: If installing under pavers on a concrete sub-base or slurry, do not use a Direct Burial loop. Use this Saw-Cut loop instead. Sandwiching wire between two hard surfaces will eventually cause failure.
