National Loop Co. 34' (5' X 12') Direct Burial Vehicle Detection Loop with 20' Lead-In for 17' Wide Driveways - K-NL17-14-20

Made for new paving projects, the National Loop Co. 34' Direct Burial Vehicle Detection Loop with 20' Lead-In is a factory-wound 14 AWG loop that installs flat on the graded sub-base. 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. Since the conduit protects the wire, the loop sits directly on the sub-base and gets buried under the new asphalt, concrete, or gravel surface. Its 12' side spans the travel lane while the 5' side runs in the direction of traffic, leaving roughly 2' 6" of clearance on each edge, an arrangement well suited to 2-car drives in newer subdivisions and homes with boat or trailer parking.

Features:

• Works wherever vehicles need detecting: automatic gates, parking barriers, overhead doors, traffic signals, arming devices, and vehicle counters
• One continuous, non-spliced wire runs through the loop turns and lead-in, eliminating splice failures
• 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
