Description

The CURT 57720 is a trailer wiring adapter designed to bridge the gap between a 7-way RV blade vehicle socket and a 6-way round trailer plug. It features a center pin specifically for brake lights. This adapter includes an integrated backup alarm that provides an audible signal when the vehicle is in reverse and a dust cover to protect the connector from environmental elements. The product is covered by a one-year limited warranty.
