4.76 Feet Length Strut Channel Trolley Track，1-5/8" Wide and high 12 Gauge Metal Steel U Channel with Thick Galvanized Steel Strip Groove Back, Sturdy and Durable. (Pack of 2)

Works great with Vevor hoist !!

I'm using jacks to shore up three joists on 2' centers, with paired channel struts across, both on the ground and bearing against the joists. Four-foot channels would be a little too short, so I was pleased by the length of these. I would have preferred solid back rather than perforated, but perforated wasn't a problem.No way to pour a proper footing in the crawl space, but the ground is dry and hard, good enough, I hope. I wanted to put down a poly underlayer to reduce the possibility of rust in case of moisture, and found that I needed to file off the sharp edges at the ends, where they were cut to size with a saw. Not a big deal.Good product. I got what I expected. No surprises.

Excellent for supporting wenches. The track goes well with a variety of wheels. The track is the right size to attach to 2x4's.

Pity there are few hole options, but this is a great winch trolley rail.

This rail is really sturdy, work's great.

Very heavy duty track section. The protective end caps are available for sale also on Amazon.

Strong/well made.
