National Loop Co. 17' (2.5' X 6') Direct Burial Vehicle Detection Loop with 100' Lead-In for 8.5' Wide Driveways - K-NL8.5-14-100

Designed to be paved over, the National Loop Co. 17' Direct Burial Vehicle Detection Loop with 100' Lead-In is a preformed 14 AWG inductive loop for new-surface installations. Teamed with a loop detector, it gives the gate operator the presence detection UL 325 counts as one of its two means of entrapment protection, so the gate reverses or holds open while a vehicle sits in the path. 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 6' side spans the travel lane while the 2.5' side runs in the direction of traffic, leaving roughly 1' 3" of clearance on each edge, an arrangement well suited to older urban row homes, narrow driveways, and single-car gravel drives in rural areas.

Features:

• 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
• 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
