National Loop Co. 42' (6' X 15') Direct Burial Vehicle Detection Loop with 50' Lead-In for 21' Wide Driveways - E-NL21-18-50

National Loop Co. 42' (6' X 15') Direct Burial Vehicle Detection Loop with 50' Lead-In for 21' Wide Driveways - E-NL21-18-50

Monitoring the driveway around the clock, the National Loop Co. 42' Direct Burial Vehicle Detection Loop with 50' of lead-in to reach the detector covers one of the two means of entrapment protection written into UL 325. Crews place it on the graded base, then pave right over it with asphalt, concrete, or gravel. A 6' x 15' arrangement gives it 42' of total wire, matching 21' wide driveways at wider rural and farm gate entrances plus room for guest parking.

National Loop Co. 42' (6' X 15') Direct Burial Vehicle Detection Loop with 50' Lead-In for 21' Wide Driveways - E-NL21-18-50

Placed before the paving crew arrives, the National Loop Co. 42' Direct Burial Vehicle Detection Loop with 50' Lead-In is an 18 AWG inductive loop that disappears under the finished surface. Connected to a loop detector, it reports every vehicle that crosses the sensing area, giving the gate operator the non-contact detection that fills one of the two UL 325 entrapment protection slots. Because it ships encased in heavy-duty, liquid-tight conduit, the loop lays directly on the graded sub-base and is then paved over under fresh asphalt, concrete, or gravel. Its 15' side spans the travel lane while the 6' side runs in the direction of traffic, leaving roughly 3' of clearance on each edge, an arrangement well suited to 2-car plus guest parking and wider rural/farm gate entrances.

Features:

  • Liquid-tight conduit stands between the wire and sharp stones, chemicals, ground movement, and harsh weather
  • Arrives fully assembled and ready to install under new asphalt, concrete, or gravel
  • Factory-set turn count means optimal read range without any on-site adjustment
  • More cost-effective than hand-wound loop installations
  • Fills the non-contact detection role UL 325 assigns to vehicle loops in a 2-device entrapment protection system
  • Designed for vehicle detection with gate operators, parking barrier gates, overhead doors, traffic signals, arming devices, and vehicle counters
  • Wound from one continuous, non-spliced wire, leaving no splice point between the loop and lead-in to fail
