National Loop Co. 20' (4' X 6') Direct Burial Vehicle Detection Loop with 175' Lead-In for 10' Wide Driveways - E-NL10-18-175

Placed before the paving crew arrives, the National Loop Co. 20' Direct Burial Vehicle Detection Loop with 175' Lead-In is an 18 AWG inductive loop that disappears under the finished surface. Working through a compatible loop detector, it detects the metal mass of vehicles above, satisfying the non-contact detection that UL 325 lists as one of its two required means of entrapment protection. The pave-over design means no slot cutting: the loop goes down on the graded base and the fresh surface finishes the installation. Its 6' side spans the travel lane while the 4' side runs in the direction of traffic, leaving roughly 2' of clearance on each edge, an arrangement well suited to standard single-car suburban homes, duplex driveways, and small farm entrances.

Features:

• Wound from one continuous, non-spliced wire, leaving no splice point between the loop and lead-in to fail
• Heavy-duty, liquid-tight conduit shields the loop from sharp stones, chemicals, ground heaving, and harsh weather
• Fully assembled at the factory, so there is nothing to wind, count, or connect before paving
• Predetermined number of turns removes the guesswork of achieving optimal read range
• Saves labor cost compared with winding a loop by hand in the field
• Provides the non-contact vehicle detection UL 325 gate systems count toward their two required means of entrapment protection
• Works wherever vehicles need detecting: automatic gates, parking barriers, overhead doors, traffic signals, arming devices, and vehicle counters
