CURT Tailgate Sensor
CURT Tailgate Sensor

CURT has launched the NO-SPLICE, Protective MultiPro / Multi-Flex Tailgate Sensor towing solution for the GMC MultiPro and Chevrolet Multi-Flex tailgates. The sensor is designed to require no wire cutting or splicing on the truck.

Instead, it uses a factory-style wiring harness to plug into OEM sockets. Once installed, it is constructed to prevent the inner tailgate panel from dropping down while a ball mount or other towing accessory is installed in the receiver. It is manufactured to allow for full use of the truck’s cargo and towing capabilities without risking an expensive repair.

Polyvance Welding Rods
Nylon Welding Rod

Polyvance announces the availability of two welding rods—a black nylon and a 15% glass-reinforced nylon.

The company's hopper/dryer machine dries hydrophilic resins like nylon, which is designed to allow for the extrusion of welding rods with the proper moisture levels for optimum quality. The black rod is constructed to allow for cosmetic restoration of the welded parts without the need for paint.

Glass-reinforced nylons are often used under the hood, with radiator tanks, intercooler tanks, radiator supports, and intake manifolds being common examples.
