Selecting the right trailer hitch, ball mount and trailer ball to manage the weight of your trailer is not the only important aspect of towing; you also need a trailer that can stand up to the road ahead. That means equipping it with a coupler that is built to go the distance. CURT straight-tongue couplers, featuring our Posi-Lock latch, are the most common type of trailer coupler. With a mounting channel designed to fit onto a straight trailer tongue, the Posi-Lock coupler is easy to install. It is made from hardy steel construction and has a durable zinc finish to protect from corrosion, wear and tear. The lockable latch mechanism on CURT Posi-Lock couplers is easy to operate and adjusts by tightening or loosening a simple bolt. This CURT straight-tongue coupler features a gross trailer weight capacity of 2,000 lbs. and a tongue weight capacity of 200 lbs. It has a 2" channel and fits a 1-7/8" diameter trailer ball. All CURT couplers include a limited lifetime warranty and feature a lockable latch to give you peace of mind. ## Features - PRECISE FIT — This trailer coupler is designed to mount onto a 2-inch wide trailer tongue beam and couple to any standard 1-7/8-inch diameter trailer ball - EASILY ADJUSTABLE — Equipped with a posi-lock spring and adjustable nut on the inside, this trailer hitch coupler can easily be adjusted to ensure a snug fit on the trailer ball - SECURE COUPLING — The posi-lock latch mechanism of this trailer tongue coupler accepts a safety pin or coupler lock for enhanced security - HIGH-STRENGTH — Constructed from punched, die-cut steel, this trailer ball coupler is rated as a class 1 trailer coupler and has a capacity of 2,000 lbs. gross trailer weight and 200 lbs. tongue weight - CORROSION-RESISTANT — To easily outlast the elements, including rain, snow, dirt, road grime and more, this straight tongue trailer coupler is finished in a durable zinc plating and makes a great boat trailer coupler ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0007LZGX8 | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #248,127 in Automotive ( See Top 100 in Automotive ) #157 in Trailer Coupler Parts | | Brand Name | CURT | | Compatible with Vehicle Type | Marine-Personal-Craft, Trailer | | Customer Reviews | 4.6 4.6 out of 5 stars (516) | | Finish Type | CLEAR ZINC | | Global Trade Identification Number | 00612314115112 | | Included Components | Straight Coupler | | Item Type Name | Accepts 1-7/8-Inch Hitch Ball, 2,000 lbs. | | Item Weight | 2.5 pounds | | Manufacturer | Curt Manufacturing | | Manufacturer Part Number | K5128 | | Manufacturer Warranty Description | Limited Lifetime Warranty (One-Year Finish, One-Year Parts) | | Material Type | Alloy Steel | | Maximum Towing Capacity | 2000 pounds | | Model Number | 25128 | | Number of Items | 1 | | OEM Equivalent Part Number | 25128 | | UPC | 612314115112 | | Unit Count | 1 Count | ## Product Details - **Brand:** CURT - **Finish Type:** CLEAR ZINC - **Item Weight:** 2.5 pounds - **Material:** Alloy Steel - **Vehicle Service Type:** Marine-Personal-Craft, Trailer ## Images ![Curt Manufacturing K-5128 Class 1 2000 Gtw 1 7/8 in Ball 2 in Channel Zinc Plated - Image 1](https://m.media-amazon.com/images/I/61vo42wwz3L.jpg) ## Frequently Bought Together - CURT 25128 Straight Tongue Trailer Coupler for 2-Inch Channel, 1-7/8-In Hitch Ball, 2,000 lbs - CURT 40001 Chrome Trailer Hitch Ball, 2,000 lbs, 1-7/8-Inch Diameter, 3/4 x 1-5/8-Inch Shank, Silver - CURT 25094 Posi-Lock Coupler Replacement Latch for 1-7/8-Inch Trailer Hitch Ball --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/16823984-curt-manufacturing-k-5128-class-1-2000-gtw-1-7](https://www.desertcart.be/products/16823984-curt-manufacturing-k-5128-class-1-2000-gtw-1-7) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-26*
