BD Loops Direct Burial Preformed Vehicle Detection Loop
The BD Loops Direct Burial Loop is a premium preformed vehicle detection loop designed for gate operators and access control systems. Built with solid 16AWG wire, these loops are engineered for direct burial under concrete, asphalt, pavers, or gravel roads — no PVC pipe required.
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 perimeter.
Key Features & Benefits
- Solid 16AWG wire – creates a rigid loop that won’t sag below rebar
- No air pockets – dramatically reduces phantom detections and detector lock-up
- Directional arrows on wire + red/black lead-in for easy phasing
- Twisted jacketed lead-in prevents “coil back” and saves installation time
- 135° wide-angle night vision camera (wait, no — correction for this product: extreme climate range -4°F to 122°F)
- Includes full installation kit: cable ties, ground stakes, stickers, and instructions
Recommended Minimum Size
- Minimum 3 feet wide for standard vehicles
- Wider (4–6 ft short leg) recommended for taller vehicles or commercial use
Installation Tips
- Offset loop from rebar pattern and tie down with supplied cable ties
- Run lead-in through conduit and glue joints with PVC solvent cement
- Fully encase loop in sand when installing under pavers or in gravel
- Remove ground stakes before final burial in gravel or dirt roads
Important: If installing under pavers on a concrete sub-base or slurry, use a BD Loops Saw-Cut loop instead. Sandwiching wire between two hard surfaces will eventually cause failure.
