National Loop Co. 42' (6' X 15') Direct Burial Vehicle Detection Loop with 75' Lead-In for 21' Wide Driveways - X-NL21-14-75

Placed before the paving crew arrives, the National Loop Co. 42' Direct Burial Vehicle Detection Loop with 75' Lead-In is a 14 AWG inductive loop that disappears under the finished surface. 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. Installation is a lay-and-pave job: set the loop on the graded sub-base, run the lead-in to the detector, and let the paving crew cover it. With the 15' side crossing the lane and about 3' of clearance per edge, and the 6' side capturing vehicles in the direction of travel, the layout fits 2-car plus guest parking and wider rural/farm gate entrances.

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
