6 Pcs 4 Hole T Shape Connector Flat Plate Bracket for 1-5/8" Strut Channel, 3/16" Thick

These plates are very thick and will provide excellent support when joining struts together for mounting my solar array.

They fit and work well holding unistrut pieces together

Much heftier than expected. I ordered the wrong type for the super strut but we made it work.

Heavy duty. Connected frame together.

Works fine just thin

This is not the same size of standard Unistrut. Overall dimensions are smaller, material is thinner, hole size is smaller

The Wolf Outlet reviewer is correct -- these are thinner and cheaper than genuine Unistrut or Superstrut product. They're about 1/16" smaller in thickness as well as outside dimensions. Though the holes do appear to be smaller, a standard 1/2"-13 bolt fits with adequate clearance. The galvanized finish may also be inferior to genuine product. I have them in a outdoor application where they're exposed to rain and haven't noticed ccorrosion yet, but time will tell.A single Unistrut flat tee cost sold by Amazon goes for $10, though they cost around $7.50 - $8.00 from Grainger & other industrial suppliers. These cheap knock-offs are about $3.00 ea.So it's a question of value. If you're building something that is going to be subject to high loads and/or meet stringent construction requirements, you might need genuine product that is backed up with OEM's engineering specifications. But if you're doing a simple household job/hobby that doesn't come close to challenging the strength of the metal, these will work and save money.
