National Loop Co. 20' (4' X 6') Direct Burial Vehicle Detection Loop with 250' Lead-In for 10' Wide Driveways - X-NL10-14-250

Contractors laying new asphalt, concrete, or gravel can set the National Loop Co. 20' Direct Burial Vehicle Detection Loop with 250' Lead-In directly on the sub-base and pave right over it. Working through a compatible loop detector, it detects the metal mass of vehicles overhead, satisfying the non-contact detection that UL 325 lists as one of its two required means of entrapment protection. Because it ships encased in heavy-duty, liquid-tight conduit, the loop lays directly on the graded sub-base and is then paved over under fresh asphalt, concrete, or gravel. Formed as a 4' x 6' rectangle, it centers in the lane with about 2' of clearance per edge, a proportion that suits standard single-car suburban homes, duplex driveways, and small farm entrances.

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
