Product Description

Master Lock model 389DAT — a universal trailer coupler lock designed to fit most 1-7/8" (48 mm), 2" (51 mm) and 2-5/16" (59 mm) ball couplers. Steel construction with a rust- and corrosion-resistant finish (manufacturer lists a red / red-brass variant), an advanced locking mechanism that resists picking and prying, and easy install/remove operation. Package-content listings show the lock ships with two keys and is sold as a single unit; Master Lock backs the product with a limited lifetime warranty. (Model: 389DAT — SKU preserved as provided: 071649263019.) Based on current national retail offers (Academy $29.99, Home Depot $32.49, Northern Tool $34.99, Master Lock store $35.99 — sources below) a competitive local resale price for Dayton, IA 50530 would be approximately $33.00 USD each (rounding the market median of ~$33.74 to a simple, buyer-friendly price), which undercuts some retail listings while remaining near typical street price.
