Features to know about

Quick Bed Access: Folding Tri-Fold Design

When you’re loading gear or grabbing tools, you don’t want to fight with a bed cover. The Trifecta ALX folds up fast—just lift at the tailgate and secure the rear and center panels to open two-thirds of the bed. That gives you room for bulky cargo without removing the cover. When you’re done, it folds back down in seconds and locks automatically as it makes contact with the bed.

Fast Operation: Secure Rotary Release Latching System

Getting in and out of the bed is quicker thanks to the rotary release knob at the rear driver side. Rotate and lift to unlock, then fold the cover forward. The release is easy to reach and eliminates the need for tailgate clamps. When closed, the auto-latching system secures the cover, so it stays tight and locked without extra steps.

All-Season Protection: Heavy-Duty Ancona Pebble-Grained Fabric

Rain, dirt, and dust stay out with the durable Ancona fabric and adhesive-free perimeter seals. The material keeps its shape and blocks out the elements while maintaining a clean look. Whether it’s a downpour or a dusty trail, your cargo stays protected under the tough, weather-resistant surface.

Built to Last: Aircraft-Grade Aluminum Frame

Under the fabric is a rustproof, black powder-coated aluminum frame that holds strong without weighing the truck down. It’s sturdy enough to handle years of folding and unfolding while keeping the cover aligned and secure. And when you need to remove it completely, no rails stay behind—it’s self-contained and weighs about 35 lbs for easy handling.

Simple Setup: Tool-Free Installation

Mounting the Trifecta ALX doesn’t require drilling or special tools. Sturdy T-handle clamps secure the front panel to the bed flanges at the cab, and the rest locks into place automatically. It’s ready to use right out of the box and backed by a lifetime warranty for long-term confidence.

Fit was perfect for the 2024 Honda Ridgeline with just a minor rubbing of the truck in-bed trunk lid on the side rails when fully opened.

As usual, the eTrailer installation videos were a life-saver and always better than those from the manufacturers. Very clearly shows full installation process with cautions and detail. This, and competitive prices, are the primary reasons for my always buying through eTrailer when my items are available.

2022 Honda Ridgeline
First time truck owner, and first time with a bed tonneau cover. Installation went well, but the side rail interferes with the opening of the Ridgeline's in-bed trunk cover. There is very little lateral adjustment on the side rail, and I have it pushed over as far as it can go. Only hits on one side, and it scrapes the rail. Does allow the trunk cover to open fully, but... Called Extang and they said that was to be expected. Would have been good to know ahead of time. Otherwise, satisfied with the build quality and operation (so far).

Top sags and catches water like a bird bath.
If it was tighter it would be a better top.
