Review on 4 E-Track Wood Beam End Socket Shelf Brackets with E Track Fittings, Ideal for 2x4 & 🔩 2x6 in Trucks, Trailers, Vans, RVs, Cargo Tie-Down Systems, ETrack Tiedowns for Custom Load Bars, Handmade Cabinets, and Shelves by Sean Chambers

So I needed a shelf in the front of the trailer. Downstairs generators and vacuum cleaners, upstairs buckets. I had gauge I on the sides and found these 2x4 holders that fit perfectly. Decided to try them. Wow, they just did this job. Mount bushings deployed, pair of 8ft 2x4s deployed. I attached it with screws, added an MDF shelf, attached it with screws, some spacers in the middle and you're done. I'm impressed, I didn't know it existed. I've found some other attachments that I keep track of as I view and use them. The durability is only rated a 4 because they are not as strong as other lures I have. But they seem to be doing their job.
