Overview

The Brophy ETR4 is a removable tie-down O-ring designed for compatible E-track cargo-control systems. Its all-metal construction, zinc finish and 2" inside-diameter ring provide a practical anchor point for compatible straps and hooks. The fitting can be positioned in an available E-track slot and moved when the cargo configuration changes.

R&P Service Insight

A movable E-track anchor gives you more flexibility than a permanently mounted tie-down point, especially when hauling cargo that changes in size or position.

  • Inspect the Track: Make sure the chosen E-track slot is clean, straight and free of damage before inserting the fitting.
  • Confirm Engagement: After installation, pull firmly on the fitting to verify that the spring mechanism is fully locked into the track.
  • Rate the Entire System: The usable system capacity is determined by the lowest-rated fitting, strap, hook, rail, fastener or mounting surface.

R&P Knowledge Hub

Compatibility: The ETR4 is designed for standard E-track cargo-control systems. It is not intended for unrelated track profiles or proprietary rail systems that do not use standard E-track slots.

System Fit: E-track is commonly installed in enclosed trailers, cargo vans, service vehicles, garages and other hauling applications where adjustable cargo anchor points are useful.

Installation Notes: Pull back the spring-loaded release, insert the fitting into a compatible E-track slot and release the mechanism. Confirm that both ends are seated securely before attaching cargo-control equipment.

Performance Insight: The 2" inside-diameter ring creates a versatile connection point while the removable fitting allows the anchor location to be adjusted without permanently modifying the track.

Brand & Fitment Note

Selling Brand: C.R. Brophy Machine Works

Manufacturer Part Number: ETR4

Product Identification: This listing is for one Brophy ETR4 zinc-finished, 2" inside-diameter O-ring fitting rated by the manufacturer at 4,000 lb.

Before Ordering: Verify that your application uses standard E-track and that the ring size, fitting style and stated capacity are appropriate for your cargo-control setup.

R&P Repair Insight

If an E-track fitting feels loose or will not lock securely, inspect both the fitting and the rail before use. A rated fitting cannot compensate for damaged track or an improperly mounted cargo-control system.

  • Check the Spring Clip: The release mechanism should move freely and return to the locked position when released.
  • Inspect the Slot: Do not use a track position that is bent, enlarged, cracked or heavily corroded.
  • Review the Installation: Track capacity also depends on the fasteners, spacing, backing structure and surface to which the rail is mounted.
