Essential Info

It can be difficult at times navigating your Truck, RV, Van, Large SUV, or Extended Cab Truck into tight spots. Sometimes a mirror just won't give you all the information you need to confidently park your rig. Steelmate USA provides an easy fix for such a situation with the PTS4000D Parking Assist Sensor, exclusively designed for large vehicles with metal bumpers. The sensors install into your vehicle's rear metal bumper and use Ultrasonic Sound-Wave Technology to register objects as far as five feet away. Avoid getting an embarrassing, frustrating, and expensive ding from objects you can't see as you attempt to reverse-park your sweet ride. The PTS4000D was designed to install clean and includes a 4-Stage piezo alarm that lets you know when you're getting too close to something you probably don't want to hit. Rest easy knowing you can park confidently!
