National Loop Co. 17' (2.5' X 6') Direct Burial Vehicle Detection Loop with 250' Lead-In for 8.5' Wide Driveways - X-NL8.5-14-250

For driveways getting a fresh surface, the National Loop Co. 17' Direct Burial Vehicle Detection Loop with 250' Lead-In provides vehicle detection without cutting into the finished pavement. 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. Crews place the loop on the prepared sub-base before paving, and the new asphalt, concrete, or gravel surface locks it in place. 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:

• 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
• 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
