CURT SecureLatch Lunette Rings: 48625, 48626 & 48641 Kit

CURT SecureLatch lunette rings have an integrated drop-in pin that can accept a padlock while the trailer is disconnected. The pin turns 90 degrees out of the coupling path for towing. Although the three products below use 3-inch inside-diameter eyes, they do not share the same mounting channel. Choose by the bolt arrangement, channel opening, installed rating and whether you need a ring alone or a complete assembly.

Choose the correct SecureLatch configuration

48625 · Two mounting holesA 25,000 lb-rated lunette ring for a separately sourced 11¾-inch-high channel with a 3-inch inside width. The channel, appropriate mounting hardware and pintle connection must be checked individually.
48626 · Three mounting holesA 40,000 lb-rated ring that specifically requires channel 48651 with a narrower 2¾-inch opening. The ring-only installation sheet calls for three Grade 8 mounting-bolt sets, supplied separately.
48641 · Complete ring-and-channel kitThe 40,000 lb-rated package includes ring 48626, its matching 48651 channel and three 5/8-inch Grade 8 bolts with washers and locking nuts.

CURT SecureLatch ring and kit comparison

MPN Configuration Eye Mount Channel GTW
48625 SecureLatch ring only 3 in Two-hole 11¾-in-tall, 3-in inside-width channel 25,000 lb
48626 SecureLatch ring only 3 in Three-hole CURT 48651; 2¾-in inside width 40,000 lb
48641 Ring, channel and mounting kit 3 in Three-hole Included 48651; 2¾-in inside width 40,000 lb

Why channel size and hole count matter

The 48625 uses two mounting holes and requires an 11¾-inch-high, 3-inch-inside-width channel of adequate rating. The 48626 uses a three-hole mounting design for CURT 48651, which has a 2¾-inch inside width. The separate 48651 channel is included with kit 48641. The standard 3-inch channels 48610 and 48650 are not substitutes for 48651.

Do not assume that a channel with similar dimensions has enough capacity for the selected ring. A ring's individual rating never raises the capacity of a lower-rated channel, trailer structure, hitch or tow vehicle.

Mounting orientation is a safety requirement. CURT's installation sheets for 48626 and 48641 specify rise-position-only use: do not install either in the drop orientation. Their marketing descriptions discuss an offset base, but installation must follow the exact current instruction sheet. CURT lists a 180 ft-lb mounting-bolt torque for these models' specified 5/8-inch bolts; do not apply that value to unrelated parts.

Before purchasing or installing

  1. Confirm the intended hitch connection. These 3-inch inside-diameter eyes require an appropriately rated pintle hook or other manufacturer-approved pintle connection; a conventional hitch ball alone is not an interchangeable coupler.
  2. Measure the channel opening and hole pattern. Separate the two-hole, 3-inch-width 48625 system from the three-hole, 2¾-inch-width 48626/48641 system.
  3. Confirm the supplied package. The 48625 and 48626 are ring-only products. The 48641 kit contains the ring, channel and specified fasteners. The separate 48626 installation sheet identifies its mounting bolts as not included.
  4. Follow the permitted orientation. CURT restricts 48626 and 48641 to the rise position. Do not flip them into drop orientation for towing.
  5. Have structural installation performed correctly. CURT's 48641 instructions require the channel to be welded to a suitable rated structure by an AWS-certified welder, with proper bolt torque, safety chains and routine inspection.
