SKTREX 1-5/8" 12 Gauge Metal Strut Channel, Slotted Back, Pre-Galvanized Zinc 5 Foot Length (2)

Not sure what 5 Feet length means in the description, It definitely doesn't mean the product is 5 feet long, because it isn't.

I ordered the rollers and hangers in the fall. This summer I finally have the time to try and install the hangers and rollers. The rollers are said to work with 1 5/8” electrical track, it won’t. The illustration shows 33mm or 1.299 inches. Measuring the inside of the 1 5/8” track is 1.39 inches so you have a 0.10 inch clearance, side to side. I was able to get one set of rollers into the electrical track I purchased at Home Depot but it would only start in and not roll. So I purchased the track from the manufacturer of the hangers and rollers. I needed longer bolts to hang a steel bar from. The bolts that come with the rollers are too short, no problem I’ll just get some thread all rod and cut it to length. What I learned is that there’s very little clearance between the chassis for the rollers and the track. A standard nut is too thick/tall so you’ll have to grind it down. I purchased 6-5 (58”) foot sections that are only 58 inches long. So if you are trying to install this in a steel garage with the frame on 5 foot spacing you’re going to need to build a steel support for the tracks. What I’m going to do is turn the electrical track upside down and use longer bolts to attach it to the framing and then use the slotted holes in the electrical track to hang the hanger for the roller track. That way I’ll be able to bridge the gaps because the new tracks are only 58 inches long. So on my 30 foot building I’ll be 1 foot short. I’ll modify what I have to work with but a few days project has turned into several weeks of climbing up and down scaffolding and waiting for other parts to arrive and running to get different bolts. It will be handy to have an overhead chain hoist in my garage.

There not consistent in the length, some of them are wider some narrow. Make for extra work for anyone buying these.

Worked well , got all the pieces I needed, rails , connector, stops for rail end , hanging hooks with trolly.

I bought this to build a sliding gate. Although it works, it is very rough inside the track, as the surface of this track has a serration on the rolling edge. This causes the trucks to make a lot of noise when opening/closing the gate. Also the the inside of the track is not 100% flat. It has some high and low spots which causes the gate to take more or less pressure to slide. Perhaps this is typical of this product, but I will be looking for this material from my local metal supply and replacing these.
