Description

The CURT 57185 is a 4-way flat vehicle to 7-way RV blade trailer electrical adapter designed to bridge the gap between mismatched trailer and vehicle connectors. This adapter allows a 4-way flat vehicle socket to connect with a 7-way RV blade trailer plug.

Constructed from high-strength steel with a diecast metal build, it includes a spring-loaded dust cover to protect the connector when not in use. A steel bracket is provided for secure mounting. Some manual wiring is required for installation.
