Features to know about

Fast Bed Access: Secure Rotary Release Latching System

Getting to your gear shouldn’t take extra steps. The Trifecta ALX speeds things up with a Secure Rotary Release Latching System right at the tailgate. Just rotate the release knob on the driver’s side and lift. The automatic latching feature locks the panels back in place when you close the cover, so there’s no need to mess with tailgate clamps.

Everyday Cargo Protection: Heavy-Duty Ancona Pebble-Grained Fabric

Rain, dirt, and dust stay out thanks to the new Ancona pebble-grained fabric. It’s thick, durable, and made to handle year-round conditions while keeping your truck bed dry. The adhesive-free perimeter seals fit tight against the rails to help block out moisture, so your tools, groceries, or weekend gear stay protected.

Built to Last: Aircraft-Grade Aluminum Frame

The frame and bows are made from aircraft-grade, rustproof aluminum with a black powder coat finish. That combination keeps the cover strong but lightweight—about 35 lbs—and it won’t warp or corrode over time. The panels fold easily, and the sturdy T-handle clamps hold the front panel secure against the bed flanges.

Full-Bed Functionality: Tri-Fold Design

When you need more space, just fold the rear and center panels forward to open up two-thirds of the bed. You can haul larger items without removing the whole cover, and when it’s time to get back on the road, it folds flat again in seconds.

Simple Setup: No Tools or Drilling

Installation is quick because the Trifecta ALX is completely self-contained. There are no rails to mount or parts left behind once removed. Just set it in place, tighten the clamps, and you’re ready to go.

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.
